Question

I got a question and the solution. Just don't know how the T1 was calculated = 716 because when I put it into the calculator it showed a different answer. It happen to the answer of T3 too

The section of scaffolding is L1.50 m in length, has a ms 33.0 kg mass and is supported by three ropes as shown. Determine the magnitude of the tension in each rope when a person with a weight of WP = 640 N is a distance d 0.700 m from the left end. Since the scaffolding is in equilibrium, we expect to use the first and second condition of equilibrium. Since the second condition of equilibrium involves torque, before starting the problem, see if you can write an expression for the torque in terms of the force producing the torque, the magnitude of the vector which locates the point of application of the force relative to the point about which we are taking the torques, and the angle between the direction of the force and the vector which locates the point of application of the force. In order to determine the torques, we have to establish the point about which we are going to determine the torques. What is a convenient choice for the point about which to determine the torques? Using this specified point, see if you can write a second condition of equilibrium statement that will allow you to express the tension Ti in terms of known quantities. N magnitude of T1 For the first response in this problem, you determined the tension T . Now that you know the value of the tension T1 , see if you can write a vertical first condition of equilibrium statement that will allow you to express T2 in terms of T1 and other known quantities. N magnitude of T2 For the first response in this problem, you determined the tension T-Now that you know the value of the tension T1 , see if you can write a horizontal first condition of equilibrium statement that will allow you to express magnitude of T3 in terms of Ti and other known quantities. N 40.0 0.700 m 1.50 m

Explanation / Answer

calculating the expression as given , we get the value T1 = 716 and T3 = 549

make sure that the calculator is set to degree mode. the angles there are in degree
