Member ABC, which is supported by a pin and bracket at C and a cable BD, was designed to support the 20-kN load P as shown. The pin at C has 20 mm diameter. a) Draw complete free body diagram of member ABC and determine all forces acting upon it b) If pin at C was made from steel with ultimate shear stress 300 MPa, calculate its factor of safety c) Knowing that rope BD made of a material has allowable stress of 50 MPa, calculate its diameter d) Use the information in part c, find the Young’s modulus of the rope material knowing that its length is 0.5 m and stretched by 0.5 mm upon the shown loading.
