the pulley shown below is massless and frictionless. if the system is released from rest from the position shown, which of the following statements are true (more than one answer can be correct). since block b is larger and heavier than block a, the pulley will rotate clockwise.

Respuesta :

A massless string crosses a frictionless pulley while carrying two masses at its ends: m and me (m;> m.

What exactly does it mean when a pulley has no friction?

When we say a pulley is frictionless, we mean that there is little to no friction in its bearings, which allows the pulley to rotate freely and without encountering any resistance. We don't want to imply that there is little to no friction between the string and the surface of the pulley.

How can the tension be determined in a frictionless pulley system?

The following equations are used to determine the tension T = M x A. If you are attempting to determine T in a simple pulley system with a mass of 9g and an upward acceleration of 2m/s2, then T = 9g x 2m/s2 = 18gm/s2
