A 1,0007N uniform boom at q) = 70.0\" to the horizontal is supported by a cable at an angle 6 = 20.0 to the horizontal as shown in the figure below. The boom is pivoted at the bottom, and an object of weight w : 2,450 N hangs from its top. (a) Find the tension in the support cable. :w (b) Find the components of the reaction force exerted by the pivot on the boom. (Assume the positive Xedirection is to the right and the positive yidirection is upward. Include the sign of the value in your answer.) horizontal component l: kN vertical component E kN Need Help
