ENGR 476 Mechanics of Materials II
Assignment 4
1. A 72-kg diver jumps from a height of 0.5 m onto end C of a diving board having the uniform
cross section shown. Assuming that the diver’s legs remain rigid and E=12 GPa, determine (a)
the maximum deflection at point C, (b) the maximum normal stress in the board, (c) the
equivalent static load.
2. Each member of the truss shown is made of steel and has a cross-sectional area 400 mm2. Using
E = 200 GPa, determine the deflection of D caused by the 16-kN load.
5. For the uniform beam and loading shwon, determine the reaction at support.
