A beam is supported by a pin at point A and a cable that passes through a pulley at point D. There are also two rollers supporting it at points E/F. D 0.5 m E A B F 60 kg 0.4 m -0.4 m -0.4 m Figure 3.1: Beam with pulley a) Assuming that the pulleys are small, i.e., their radii are small compared to the dimensions of the structure, and friction is neglected, calculate the reactions at the rollers (EF) and at the pin at A. b) Calculate the internal resultant loadings at the midpoint of segment AB and at the midpoint of segment BE.
