Down: 2) Test methods used to examine an object, material, or system without impairing its future usefulness.3) Of or relating to the manufacture of any product (as earthenware, porcelain, or brick) made essentially from a nonmetallic mineral (as clay) by firing at a high temperature.5) The collection and analysis of numerical data in large quantities.6) Processes that remove material to change the size, shape, or surface of a part. There are two groups of separating processes: machining and shearing.7) A measure of how easily a material can be twisted.9) A force system where all of the forces are applied at a common point on the body or having their lines of action with a common intersection point.11) Sometimes referred to as tensile strength; determined by measuring the maximum load a material specimen can carry when in the shape of a rectangular bar or cylindrical can.12) A diagram used to isolate a body from its environment, showing all external forces acting upon it.13) The ability to get answers to questions through a conscious, organized process. The answers are usually, but not necessarily, quantitative.14) A method of analysis of trusses which constructs free body diagrams of each joint and determines the forces acting in that joint by considering equilibrium of the joint pin.19) The resultant of a system of force is the vector sum of all forces.20) The turning effect of a force about a point equal to the magnitude of the force times the perpendicular distance from the point to the line of action from the force.21) Nominal stress developed in a material at rupture. Not necessarily equal to ultimate strength. Since necking is not taken into account in determining rupture strength, seldom indicates true stress at rupture.24) Any of various opaque, fusible, ductile, and typically lustrous substances that are good conductors of electricity and heat.28) A mathematical property of a cross section that is concerned with a surface area and how that area is distributed about a centroidal axis.29) The change of motion of the body is proportional to the net force imposed on the body and is in the direction of the net force.33) Operational techniques necessary to satisfy all quality requirements; includes process monitoring and the elimination of root causes of unsatisfactory product or service quality performance.34) Maximum stress that a material will withstand without permanent deformation.35) Condition caused by collapse, break, or bending, so that a structure or structural element can no longer fulfill its purpose.42) Machining a surface to size with a fine feed produced in a lathe, milling machine, or grinder.45) The geometric center of an area.46) The force acting across a unit area in a solid material resisting the separation, compacting, or sliding that tends to be induced by external forces.48) A physical quantity that has magnitude only.52) The sense of a vector is the direction of the vector relative to its path and indicated by the location of the arrow. Across: 1) If one body exerts a force on a second body, then the second body exerts a force on the first body which is equal in magnitude, opposite in direction, and collinear.4) The law stating that the stress of a solid is directly proportional to the strain applied to it.7) Graphical representation of a material’s mechanical properties.8) Returning to an original condition. The extraction and recovery of valuable materials from scrap or other discarded materials.10) The loss of the load-bearing ability of a material under repeated load application, as opposed to a single load.15) The elements, constituents, or substances of which something is composed or can be made; matter that has qualities which give it individuality and by which it may be categorized.16) The stress required to fracture a material whether by compression, tension, or shear.17) Those properties of a material that reveal the elastic and inelastic reaction when force is applied, or that involve the relationship between stress and strain; for example, the modulus of elasticity, tensile strength, and fatigue limit.18) The connection points of members of a truss.22) A condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity.23) Point at which the deformation is no longer directly proportional to the applied force. Hooke’s Law no longer applies.25) A truss composed of triangles, which will retain its shape even when removed from supports.26) A structure or body which is over-constrained such that there are more unknown supports than there are equations of static equilibrium.27) Slender straight pieces of a truss connected by joints.30) Any alteration of shape or dimensions of a body caused by stresses, thermal expansion or contraction, chemical or metallurgical transformations, or shrinkage and expansions due to moisture change.31) A systemized body of laws; a set of principles, as of ethics.32) Stages a product goes through from concept and use to eventual withdrawal from the marketplace.36) Change in the length of an object in some direction per unit.37) A plate or bracket for strengthening an angle in framework.38) The ratio of the increment of some specified form of stress to the increment of some specified form of strain, such as Young's modulus, the bulk modulus, or the shear modulus. Also known as coefficient of elasticity, elasticity modulus, elastic modulus.39) Every body or particle continues at a state of rest or uniform motion in a straight line, unless it is compelled to change that state by forces acting upon it.40) A surface or shape exposed by making a straight cut through something at right angles to the axis.41) A broad ridge or pair of ridges projecting at a right angle from the edge of a structural shape in order to strengthen or stiffen it.43) A statistical measurement of variability.44) Properties other than mechanical properties that pertain to the physics of a material and can usually be measured without the application of force.45) A strong rope, usually made of metal, designed to have great tensile strength and to be used in structures.47) A support that only prevents a beam from translating in one direction.49) Anything for which a person is legally bound or responsible.50) A body subjected to a push.51) The process of creating an object by adding small pieces or layers together to make a final product53) Test methods used to examine an object, material, or system causing permanent damage to its usefulness.54) Solid material which is composed of two or more substances having different physical characteristics and in which each substance retains its identity while contributing desirable properties to the whole; especially, a structural material made of plastic within which a fibrous material (as silicon carbide) is embedded.55) The average of the squared differences from the mean.56) The condition of a string, wire, or rod that is stretched between two points.57) The probability that a component part, equipment, or system will satisfactorily perform its intended function under given circumstances, such as environmental conditions, limitations as to operating time, and frequency and thoroughness of maintenance for a specified period of time.
