7. Blocks A and B have a mass of 100 kg and 150 kg, respectively, If the coefficient of static friction between A and B and between B and C is 0.25, and between the ropes and the pegs D and E is 0.50, determine the smallest force F needed to cause motion of block B if P = 30 N.

Identify all the forces applied in the FBD. show complete FBD and solution. 30 mins left.

A beam is loaded with a uniformly distributed load between the two roller supports and a single load at the overhang. It also has two internal hinges - one midway between the fixed support and the first roller support and the other midway between the two roller supports. Refer to the figure below for the magnitude of the loadings and dimensions. a) Draw the FBD of the beam and determine if the beam is statically determinate or indeterminate. 75 kN/m 100 KN 12.5 m 12.5 m 7.5 m 7.5 m 10 m b) If the beam is statically determinate, analyse it using the equilibrium equations. If the beam is statically indeterminate, analyse it using structural indeterminate methodologies such as setting up and solving the equations of equilibrium, equations of compatibility, and force-displacement relations. 1. Draw the FBD for each element of the beam and determine the axial forces, shear forces, and bending moments for each element. 2. Once all forces and moments are calculated, draw the FBD of the whole…
