16 1. A concentrated load is one which a) acts at a point on a beam b) spreads uniformly over the whole length of a beam c) spreads non-uniformly over the whole length of a beam d) varies uniformly over the whole length of a beam. 5. 2. Tensile load results in a) contraction 3. Shear stress. b) elongation a) acts normal to the surface b) acts tangential to the surface c) is equal to tensile stress d) is equal to compressive stress. c) bending 4. During the tightening of a nut on a bolt, the stress induced in the bolt is a) Compressive b) shear c) tensile d) bending. (b) elasticity d) twisting. The property of a material in which a body returns to its original shape after removal of the load is called: (a) plasticity (c) ductility 6. Whenever a material is loaded within the elastic limit, stress is b) directly proportional to a) Equal to (d) malleability. strain. c) inversely proportional to.
