A 1130 N uniform boom is supported by a cable perpendicular to the boom, as seen in the figure below. The boom is hinged at the bottom, and an m = 1870 N weight hangs from its top. Assume the angles to be = 69.5o and = 90.0o - . Find the tension in the supporting cable Find the x-components of the reaction force exerted on the boom by the hinge (choose to the right as positive). Find the y-components of the reaction force exerted on the boom by the hinge (choose upwards as positive). I don't understand why radius is taken into account when calculating tension, but doesn't play a role in calculating the components of force.
