Astring that passes over a pulley has a 300 kg mass attached to one end and a 450 kg mass attached to the other end. the pulley, which is a disk of radius 10 cm, has friction in its axle. what is the magnitude of the frictional torque that must be exerted by the axle if the system is to be in static equilibrium?

147 N-m

Explanation:

Given

mass of first Pulley

mass of second Pulley

radius of Pulley

If the system is in equilibrium then tension in the side mass is

Tension in side block

Net torque is

therefore Frictional Force must apply a force of 147 N-m in order to system remains in equilibrium

number of electrons for neutral cl

a. carbon monoxide from car exhaust

b.particulate matter, such as soot

c.water vapor from a factory smokestack

d.acid rain

these are the answer choices im on that question right now
