Question

a. Two forces are acting at a single point on an object. Force A has a magnitude of 8000 N and is directed due West. Force B has a magnitude of 6000 N and is directed at 400 N of E. Determine the magnitude of Force C which must act at the same point so that the object will be in translational equilibrium. b. 40° 5.0 m A 25 kg mass is suspended from the end of a 5.0 m long uniform boom. If the mass of the boom is 12 kg, what is the tension in the supporting rope? C. 10 N 30° .0m 20 N Determine the sum of the torques about the point P for the two forces show below acting on a very light wooden beam. (Ignore its weight) d. 60° The 0.10 kg metre stick shown below is held up by the perpendicular force F. The bottom of the metre stick is on the verge of sliding to the right. Determine the size of the frictional force being provided by the floor.
