The specialized wrench in the figure has a 30 lb force applied to the handle as shown. The pin at A fits in a hole in the disk and can be treated as a pin-joint. The contact at B is smooth. Using the principle of the concurrency of a three- force body, find the reactions at A and B. Be sure to report both directions and magnitudes. You must draw a FBD of the wrench as well as a force triangle. 30 1b 1 in. B 6 in
