Question

Examine the rod below. It is fixed into a wall at the left hand end. From the wall to point B is 200mm. BC is 200mm long and CD is 200mm long. (Centreline to centreline distances). Point A lies on the positive Y-axis on a cross section halfway along BC.

Three forces are applied at D. P=221.6, your individual load, is parallel to the z-axis. 400N is parallel to the y-axis and 200N is parallel to the x axis.

The rod is a tube with an 80mm outer diameter and a wall thickness of 5mm.

What is the net sigma (s) and the net tau (t) at Point A? Show all your working. Make sure you clearly indicate the direction/sign of each stress you calculate.
