I guess I'm not entirely sure of the relevant equations in this case. Perhaps the torque equation? Could the Principle of Virtual Work come into play? Again, I wasn't sure if it mattered so I redrew them all at a single location without any bearing to the drawing. After working on the...

Well, I found the torque of these two forces: τP=rxF or τ=r*Fsinθ, where r=0.71, F=50N, and θ=135° τP=25.1Nm so τtotal=50.2Nm clockwise However, this is where I get lost. Isn't the angle of F4 and the lever arm 0? And if it isn't, the equation has two variables, the distance and the angle. Is...

Homework Statement This problem is found in The Exercises for the Feynman Lectures on Physics: A flat steel plate floating on mercury is acted upon by three forces at three corners of a square of side 0.100 m. Find a single fourth force which will hold the plate in equilibrium. Give the...

Yeah, I have been using that too. I think I might need to get a more basic textbook and work through it.

Hello, I'm new to the forum and am looking for some guidance from people who have been in similar situations as me. I'm currently working in the semiconductor industry and feel dissatisfied with what I am doing. I graduated with a BS in Physics in 2014 and I am now trying to study for the pGRE...
