Question

Two flywheels of negligible mass and different radii are bonded together and rotate about a common axis (see below). The smaller flywheel of radius 28 cm has a cord that has a pulling force of 50 N on it. What pulling force (in N) needs to be applied to the cord connecting the larger flywheel of radius 48 cm such that the combination does not rotate

Answer 1

29.17 N

Step-by-step explanation:

Because of the vector notation, I wrote it down instead. It's quite pretty much self explanatory.
