A rectangular post supports a compressive load as shown in the figure. A top view of the post showing the location where the load P is applied. [b = 80 mm, h = 160 mm, ez = 55 mm, P = 125 kN] h P B b с e= What is the bending moment about the x-axis? 0 P. ex P. (ex - ez) P. (ez + e₂) P. ez ex D
What is the bending moment about the z-axis? Answer: kN.mm
What eccentricity ex would cause zero normal stress at corner B? O 102 mm O 50 mm 41 mm O93 mm ○ 56 mm
The hook shown in the figure is subjected to a force of P= 11 N that makes an angle of 0= 18° with the horizontal direction. The hook is made of a solid steel shaft with a diameter of d= 5 mm. The internal radius of the hook circle is r = 54 mm. To make the calculation simpler, assume force P is acting at the centroid of the hook circle. [0= 18°, d= 5 mm, r = 54 mm] P for What is the largest normal stress in the hook at the cut section A? Answer: MPa
