The following figure shows a simply supported beam carrying a uniformly distributed load (udl) of 10 kN/m. Assuming the beam to have a rectangular cross-section of 240 mm (b) × 400 mm (h), draw the state of stress at infinitesimal elements A, B, C and D as shown. udl = 10 kN/m NA C +-1000 1000 2000mm

The curved bar shown in the figure has a rectangular cross section of 50x75 mm and an internal radius of 125 mm. For a force F = 1200 N, determine: a-) the normal stress at point A. b-) the normal stress in point B.

1. Determine the maximum compressive and tensile stress in beam AB as shown in the figure and draw the stress distribution over the cross section at this location. 25 kN/m 5m 50 KN 5m 4 m 50 KN 150 500 450 150

The two sub questions and question g as well :

Situation The helical spring shown is axially loaded with a compression force P equal to 5 kN. The mean diameter of the spring is 100 mm and the wire used is 10 mm as indicated in the figure. 1. What is the shear stress at A? 2. What is the shear stress at B? 3. On diameter AB, locate the point of zero stress measured from C. P = 5 kN WW P = 5 kN 100mm A 10mm B
