Question
PHYSICS HELLLLPPPPA.)If you have a 140 kg person on a seesaw and they are 4 m from the pivot, and you have a 80 kg person, how far from the pivot would they need to be from the other side.
B.)Say I were to set up twin pulleys on an axis, glued together, and pulled on cords wrapped around them (see picture). Assuming the outer radius is 4 m and the inner radius is 1.5 m and the force of the inner string is 3N and the angle between them is 45 degrees, how much force do I need to apply on the outer string? (Force 2) does the angle between them matter?
( the picture is basically like a pulleys, two on top of each other. on small one and one big one)
Explanation / Answer
A)
m1.x1 = m2.x2
140 x 4 = 80 . x2
x2 = 7m
B) i can't see the picture
