A 1400-N uniform boom at ϕ = 70.0° to the horizontal is supported by a cable at an angle θ = 20.0° to the horizontal as shown in the figure below. The boom is pivoted at the bottom, and an object of weight w = 2250 N hangs from its top.
(a) Find the tension in the support cable.
kN
(b) Find the components of the reaction force exerted by the pivot on the boom.
horizontal component
kN right
vertical component
kN upward
