Signed_________________________________________________Date___________________ PROBLEM 1 . A system of three point masses (of mass 2 m , m, and m as shown) are connected via massless rigid links of length L as shown to the right with gravity pointing downward. A force F is suddenly applied to the top mass. (a) Draw a free body diagram of the assembly. (b) Assuming the assembly was at rest when the force was applied, find (the acceleration about the center of mass G) and the angular acceleration of the assembly at that first instant the force is applied. of the assembly at that first instant the force is applied....
