1. The problem statement, all variables and given/known data calculate the tension in the cable 2. Relevant equations 3. The attempt at a solution the resultant force act on the each metal bar is equal to the tension of each bar . so FR= tension in bar but , i have problem of finding the the area in FR , i have only (0.75/2) sin45(1000)(9.81) A . For A , i only know the one of the length , how to do this question ?
