1. The problem statement, all variables and given/known data A 1820N uniform boom is suppoted by a cable. The boom is pivoted at the bottom, and a 1100N object hangs from its end. The boom has a length L=13 m and is at an angle of 48 degree above the horizontal. At support cable is attached to the boom at a distance of .77L from the foot of the boom and its tension is perpendicular to the boom. Find the tension in the cable holding up the boom. 2. Relevant equations 3. The attempt at a solution 1100N * L * cos(48) + 1820N* 0.5L * cos(48) - T * 0.77L =0 Since L is not relevant in this equation you can just cancel it out. I got answer to be 1746.691583N which of course is wrong. Could you please them me what I am doing wrong.
