The rigid bar AD is supported by two steel wires of 1.5 mm diameter (E = 200 GPa) and a pin and bracket at D. Knowing that the wires were initially taut, determine the stress in each wire when a 1200 N load P is applied at D. What is the corresponding deflection of point D?

The right angle bar is supported by a pin at B and a roller at C as shown in figure. The 30 mm diameter pin is in double shear. The shear stress in the pin is limited to 120 MPa. Neglect torsional effect. 400 mm BC The maximum safe value of Pis 30° P 480 mm kN. (Round off to one decimal place)

Identify the equation for the deflection at point C.
