Atwood Machine

A pulley with mass Mp and a radius Rp is attached to the ceiling, in a gravity field of 9.81 m/s^2 and rotates with no friction about its pivot. Mass M2 is larger than mass m1. The quantities Tn and g are magnitudes. (True/False/Greater than/Less than/Equal to) The magnitude of the acceleration of m1 is ..... that of M2. (True/False/Greater than/Less than/Equal to) m1g + M2g + Mpg is ..... T3. (True/False/Greater than/Less than/Equal to) T3 is ..... T1 + T2 (True/False/Greater than/Less than/Equal to) The C.M. of Mp+M1+M2 accelerates. (True/False/Greater than/Less than/Equal to) T2 is ..... M2g. (True/False/Greater than/Less than/Equal to) T1 is ..... T2;

Explanation / Answer

(Equal to) The magnitude of the acceleration of m1 is that of M2.

(Greater than) m1g + M2g + Mpg is ..... T3.

(Equal to) T3 is ..... T1 + T2

(True ) The C.M. of Mp+M1+M2 accelerates.

(Less than ) T2 is ..... M2g.

(Less than) T1 is ..... T2;
