Question

A uniform rope of mass M and length L, is held by a thin ideal string and resting on a smooth fixed cylinder of radius R as shown.One end of the rope is exactly at the highest point of the cylinder. The string is cut now. Find the acceleration of rope just after the cut. (g=acceleration due to gravity)​

Answer 1

Answer:

mlg

Explanation:

Answer 2

The same M-weight and L-length cable, held by a small fine wire and sits on a smooth, immutable cylinder of radius R as shown. One part of the cord is at the highest point of the cylinder. The thread is cut now. Speed ​​up the thread just after cutting. (g = acceleration due to gravity):

• A small block is hung with a rope of short length at a distance of 'x' from the left end of the uniform rd length L and weight M.
• The rod is in a horizontal position and leans to the left as shown in the figure.
• Then the minimum value of 'x' (x = 0) where the initial acceleration will depend on the 'm' of the block weight.
• The same M-string and length L are fixed at its upper end from the solid support.
• Then the tension in the rope at distance l from the solid support.
• The same M-weight and L-length wire is fixed at its upper end from the solid support.
• Consider a string of weight M and length L, hanging from a solid base at the end.
• There should be a point P, length l from the solid support.
• Now we have to calculate the tension at this point.
• The easiest way to do this is to divide the cord into two piles (one above point P and the other just below it) connected by a suitable cord.
• The same L-length cable, which sits in a slightly horizontal position is pulled to the other end by force.
• "The acceleration obtained by an object crossing the Earth freely due to gravity is called the acceleration due to gravity".
• Represented by 'g'.
• This figure is independent of body composition and weight.
• Its S.I unit is m / s2.
• Suppose, for example, the area of ​​about R and its weight is M.
