A 1,400-N uniform boom at 4 = 57.50 to the horizontal is supported by a cable at an angle 0 = 32.50 to the horizontal as shown in the figure below. The boom is pivoted at the bottom, and an object of weight w = 1,750 N hangs from its top. W Pivot (a) Find the tension in the support cable. 3.87 X Your response differs from the correct answer by more than 100%. KN (b) Find the components of the reaction force exerted by the pivot on the boom. (Assume the positive x-direction is to the right and the positive y-direction is upward. Include the sign of the value in your answer.) horizontal component 3.26 X Your response differs from the correct answer by more than 100%. kN 1.061 X vertical component Your response differs from the correct answer by more than 10%.
