what would tension 1 be if W1=15N ,W2=20N and W3=150N, and Muse of k = 0.65?

To find the tension force, we need to consider the equilibrium of forces acting on the system. In this case, we have three weights (W1 = 15N, W2 = 20N, and W3 = 150N) and the tension force (T1) that is acting on the system.

The net force in the vertical direction at the point where T1 is applied should be zero, since the system is in equilibrium.

Here's how you can calculate T1:

1. Start by calculating the total weight of the system. Add up the three weights: W_total = W1 + W2 + W3.
W_total = 15N + 20N + 150N
= 185N

2. We know that the tension force is equal to the total weight of the system. Therefore, T1 = W_total.
T1 = 185N

So, the tension force (T1) in the system would be 185 N.
