The problem is I don't know how to draw the diagram.. For example, which axis of the cylinder is it talking about? (Cylinders have more than one axis, if I'm correct)
I'm really confused.
Ok, I've tried like this:
To find P rotating:
I took the moment about the centre of the sphere and obtained:
P=mu Reaction(step)
To find P slipping:
Balance:
Horiz.: P + mu (4/5) Reaction(step) + (3/4) Reaction(ground) = (3/5) Reaction(step)
Vertical: W = Reaction(ground) + (4/5)...
The end links of a uniform chain can slide on a fixed rough horizontal rod. Show that the ratio of the extreme span to the length of the chain is
mu log{[1+(1+mu^2)^(1/2)]/ mu}
Please help me!
A uniform cylinder of radius a and weight W rests in equilibrium between 2 rough planes which are both inclined to an angle pi/6 to the horizontal. The axis of the cylinder is parallel to the line joining the two planes and the coefficient of friction at both points of contact is 1/2.
Find...
Uniform sphere of radius a and weight W is resting on a horizontal ground in contact with a step of height a/5.
coefficient of friction between sphere and the ground is 3/4
coefficient of friction between sphere and the step is µ
A gradually increasing force P is applied to the highest...
