Question

The block shown in Figure 2 is subject to three forces.

a) Determine the normal stress at point A.

b) Determine the normal stress at point B.

DICE: b = 100mm; b ’= 50mm;

d = 75mm; d '= 125mm;

P1 = 500N;

P2 = 1250N;

P3 = 250N.

Disregard the weight of the block.

Please show me step by step. 

I know the answer, but I don't know how to get to it. The answer that I have is TA = -0.1703Mpa and TB = - 0,0977MPa. So can you, please, hgow to get these answers.
