1. The problem statement, all variables and given/known data The beam is supported by a pin at A and a short link BC, as shown in Figure 3.0. Determine the maximum magnitude P of the loads the beam will support if the average shear stress in each pin is not to exceed 80 MPa. The diameter for each of the pins is 18 mm. 3. The attempt at a solution diagram aswell as working are shown in the attached file.. Just want to know if by my free body diagram the shear stresses for each pin are correct?? thanks also how do you include pictures with your text?? I only know how to attach it as a pdf as image files are to big??
