Dr. Alexander is holding a briefcase with straight arm. Assume weight of the briefcase FB = 35 N, weight of the forearm FFA = 10 N, weight of the upper arm FUA = 15 N, moment arm of FB = 0.45 m, moment arm of FFA = 0.30 m, moment arm of FUA = 0.11 m, and moment arm of Fm = 0.03 m. Also, FM is 35 degrees above the horizontal. Calculate (1) muscle force FM, and (2) joint reaction forces Fj,x and Fj,y
