An object in equilibrium has three forces exerted on it. A 42 N force acts at 90° from the x axis and a 46 N force acts at 60°. What are the magnitude and direction of the third force?

I have a circular roll of paper that is 53" in diameter and weighs 2300 lbs. I am trying to determine the force required to start the roll of paper moving on a dry concrete floor. Let me know if you need any additional information. Thanks, in advance, for your help.

I need to know before tomorrow

The more direct a force is to an object will the object move farther

A 5ft by 5ft square is nailed in the bottom left corner. 3 100 pound forces are applied to the other 3 corners the force applied to the upper right corner is at a 40 degree angle What equations would be used to answer the questions below? I keep finding equations but Im not sure what all the...
