Question

A bag of cement weighting 325N hangs in equilibrium from three wires suggested in Traffic light. Two of the wires make angles ø1=60° and ø2=40° with the horizontal. Assuming the system isvin equilibrium ´find the tension T1 ,T2 and T3 in the wires.​

Answer 1

T1 = 165 [N], T2 = 253 [N], T3 = 325 [N]

Step-by-step explanation:

In order to solve this problem, we need to outline the conditions that are being described.

In the attached image we can find the sketch of the problem.

We perform a sum of forces on the Y & axis determine Equation (1). Then we perform a sum of forces on the X & axis determine Equation (2). Then we replace Equation 2 in 1 t we can find T1 then we replace in Equation (2) and we find T2. This analysis is based on Newton's third law.
