1. Figure Q1 shows an illustration of a bell crank mechanism that is in a state of static equilibrium. It is hinged at B and has a force of 200 N applied at the end c at 30° to the horizontal direction as shown in the Figure. The angle e made by the force F at the end A is 55°. a) Draw the free body diagram for the crank ABC b) Determine the force F at the joint A c) Determine the resultant force on the pin at B and its direction.

Fast please give me all answers please

9 in. 30° x 6 in. 3 in. * B 3 in. 3 in. 4 in. The top cylinder weighs 100 lbs., the middle cylinder weighs 150 lbs. and the bottom cylinder weighs 200 lbs. A) Compute the forces on the L shaped support rack from each cylinder. Include free body diagram of each cylinder. B) Compute the reactions on the L shaped support rack at A and B. Include a free body diagram of the support rack.

answer all parts

For the truss, which shows the reactions found at the supports at A and E, answer the following: a)Find the member forces at A and B using the method of joints. b)Find the member forces of CD, GD, and GF using the method of sections.   (ps. this question is from an architectural structures class, I am struggling to begin)
