Question

Which force has a larger magnitude, the pull by a cable on an elevator it is lifting or the push by a man 
on a table to change its place?

The cable from the elevator...since it's supporting 100% of the mass.

thank you :)

i just want to ask how do you figure out these stuff? please!

stormfire1 · Answer

Physics class...and life!  Think about it: would it be easier for you to push a 200lb person across the floor or to lift them with a rope?  I'd also assume that the elevator's mass is *much* greater than a table...which will require more force.

For simple problems you can think of it logically...but eventually you will need to start using the formulas :)
