Thanks Please refer to the photo below. SUBJECT: Statics of Rigid Bodies EQUILIBRIUMarrow_forward1. Three forces act on particle A located at the origin of an x-y coordinate system. Force B acts at 140o from the positive x-axis, and force C acts at 15o from the positive x-axis. The weight acts down with a magnitude of W = 100 kN. Use the equations of equilibrium to determine the magnitudes of B and C such that particle A is in equilibrium. For problems 2-5, consider the following scenario. Equilibrium of a particle: ΣF=0 ∴ ΣFx=0 and ΣFy=0. Dimensions are: h = 2.5 ft, d1 = 4.75 ft, and d2 = 3 ft. Give numeric answers to three significant figures. The load W = 50 lb.
