## Homework Statement

QUESTION 3

Assume that the pulley at A is a small frictionless pulley. The cord AB, and the cord supporting the block are made from the same cord.

Determine the maximum weight rounded down to the nearest Newton of the block that can be suspended in the position shown if each cord is only allowed to support a maximum tension 0f 1978 Newtons, and determine the angle θ.

## The Attempt at a Solution

Well, so far, I have been getting different answers. There is the exact same question in the textbook, but I am not sure if the working i did, is the same as the one in the book. I tried using the equations of equilibrium, and somehow i got that the angle is 80 degrees which is right. Could anyone give me a hint how to solve this problem? I don't even understand the question. Is value of T 1978 Newtons, or of Fab?

Also, i am guessing that T is 1978 Newtons, since to find the maximum weight, we need a maximum tension in the cable.

I tried finding W(weight) by Tcos30, but it doesn't make sense.

Any help would be appreciated.

Thank you.
