Homework Statement
The chair is 10 m from the rotating vertical axis. The solid overhang stretches 6 meters from the axis. (making 4 m from end of overhang to chair on the radial axis). The chair spins at a constant speed at 1 revolution per 10 seconds. Find the angle θ the cable makes with...
If that is the case, then why can we analysis the forces in something like an Atwood machine as if the tension on either side were equal?
for example, in the case where we know m1 and m2 (mass one and mass two), m1<m2, and T = force of tension
for m1:
ƩF = m1a
T - m1g = m1a
and...
Looking at the free body diagram of a fixed pulley with a rope going over the top half, the diagram would show tension going downward on either side and an anchor going up equaling twice the tension. I understand this is this case so the pulley doesn't move in any rectilinear motion. However...
Homework Statement
A box of mass = 20 kg rests on top of a cart mass = 30 kg. A force of 200 N is applied to the cart, and the box starts to slide. If the coefficient of kinetic friction is 0.25, what is the time it takes for the box to slide 1.5 m. Both the cart and the box start from...
