Q1: A vertical rod PQ of length L is fixed at its top end P and has a flange fixed to the bottom end Q. A weight W is dropped vertically from a height h(< L) on to the flange. The axial stress in the rod can be reduced byA
increasing the length of the rod
B
decreasing the length of the rod
C
decreasing the area of cross-section of the rod
D
increasing the modulus of elasticity of the material
ANS:A - increasing the length of the rod Stress is propotional to strain and (strain=PL/AE) thus reduction in length will decrease strain which will reduce stress. |
