Problem 1.3-5. The truss shown carries two forces: a horizontal rightward force of 50 kN and a vertical downward force of 100 kN. A roller supports the truss at A and a pin at H. If the pin's allowable shearing stress is 150 MPa, solve the pin's minimum diameter to carry the applied load safely. (Hence: The pin at A is at a state of a double shear.) D.
