Graduate How to Prove the Weighted Centroid Formula for Parallel Forces?
Given the formula for the weighted centroid, C of a system of parallel forces Fi acting at points Pi, show that two weights W and 3W, acting respectively at points P1, P2, are together equivalent to a single weight 4W acting at P, where P lies on the line segment joining P1 to P2 and P1 P : P P2...- BigCheese234

How Does a Moving Pulley Affect Acceleration and Tension in a Mechanics Problem?
Thanks for your help ! so the pulley does not effect the common acceleration? does the pulley due to its mass have any bearing on the tension of the hanging mass?- BigCheese234

Undergrad Can you do the Cross Product Backwards?
I was doing a question in a test involving the system of moments , you are given 2 force vectors and two points respectively . And you must find a third point and force to make the 3 moments in equilibrium . So I did the cross product with the first force vector and its point and then with the...- BigCheese234

How Does a Moving Pulley Affect Acceleration and Tension in a Mechanics Problem?
Homework Statement A mass 4m lying on a rough horizontal table is connected by a string, passing over a pulley, to another mass 3 m hanging freely. The pulley (regarded as a disk) has mass 4 m and rotates freely about a polar axis parallel to the edge of the table. The coefficient of kinetic...- BigCheese234
