How to Calculate the RPM of a Motor - Global Electronic Services

For a 60 Hz system with four poles, the calculations to determine RPM would be: (Hz x 60 x 2) / number of poles = no-load RPM. (60 x 60 x 2) / 4. 7,200 / 4 = 1,800 RPM. The amount of slip varies slightly based on the motor's design. A reasonable full-load speed for a 60 Hz, four-pole motor would be 1,725 RPM.

How would you calculate the force of a hammer hitting an anvil?

The force between hammer and anvil is, indeed, very difficult to calculate. There are two significantly different cases: 1) where the interaction is elastic (no permanent deformation of either the hammer or the anvil; and 2) where the interaction is inelastic (e.g., the hammer leaves a dent in the anvil).
