Having a problem figuring this out; it appears extremely easy but I would understand if rotational motion comes into play. I'm just not sure where. A cylinder of mass 2kg is rolled up an incline by means of a string arranged as shown in the figure. (incline with angle theta and a cylinder being rolled up with a string designating tention) What is the minimum force T required given that the angle of the incline to the horizontal is 30 degrees? I break it into components (up the ramp and into the ramp are negative) and can say Fx = sin(theta)mg - T = -max cheers.
