To Carry a 500-Pound Cylindrical Weight, Two Workers Lift on the Ends

Question 20

Multiple Choice

To carry a 500-pound cylindrical weight, two workers lift on the ends of short ropes tied to an eyelet on the top center of the cylinder. One rope makes a 2020 ^ { \circ } angle away from the vertical and the other makes a 3030 ^ { \circ } angle as shown in the figure below. Find the vertical component of each worker's force. Round your answer to two decimal places.
 To carry a 500-pound cylindrical weight, two workers lift on the ends of short ropes tied to an eyelet on the top center of the cylinder. One rope makes a  20 ^ { \circ }  angle away from the vertical and the other makes a  30 ^ { \circ }  angle as shown in the figure below. Find the vertical component of each worker's force. Round your answer to two decimal places.
