#1. Consider the following mass distribution where the xy coordinates are given in meters: 5 kg at (0.0, 0.0) m, 3 kg at (0.0, 4.0) m, and 4 kg at (3.0, 0.0) m. Where should a fourth object of 8 kg be placed so the center of gravity of the four-object arrangement will be at (0.0, 0.0) m?
I know that it has to be in the bottom left of the xy coordinate just didnt really know how to start the problem.
#2. A window washer is standing on a scaffold supported by a vertical rope at each end. The scaffold weighs 200 N and the scaffold is 3.1 m long. What is the tension in each rope when the 710 N worker stands 2.1 meters from one end?
Smaller tension and larger one?
I know you have the find the summation of the y forces and then the summation of the torque but I don't know whether to subtract 200 and 710. I just need some direction. Don't need an answer.
Any help would be appreciated.
