Question
The rigid bar AB is hinged at A and supported by a steel plate hanger. The hanger is fixed at C and bolted at D with two plates.Given: Width of plate hanger= 50 mm
Thickness of plate hanger = 10 mm
Bolt diameter= 20 mm
Allowable bolt shear stress= 68 MPa
Allowable bolt bearing stress= 250 MPa
a.What is the allowable stress in the hanger based on bolt capacity in double shear at D.
b.If the maximum tensile stress in the hanger is 138MPa, find the allowable load W
