2/90 The gear and attached V-belt pulley are turning counterclockwise and are subjected to the tooth load of 1600 N and the 800-N and 450-N tensions in the V-belt. Represent the action of these three forces by a resultant force R at O and a couple of magnitude
M. Is the unit slowing down or speeding up?

3:30 can you please explain to me why the angle between the y axis and the red line is 30°? i don't want to sound dumb, but i haven't understood why

[HM]

but why is it speeding up? since it's in static state?
can u explain plz!

Can you help me in this question 2/182 Three couples are formed by the three pairs of
equal and opposite forces. Determine the resultant
M of the three couples.
Problem 2/182
2/183 The combined action of the three forces on the
base at O may be obtained by establishing their
resultant through O. Determine the magnitudes of
R and the accompanying couple M.

2/184 The eyebolt supports the four forces shown. If the
net effect on the bolt is a direct pull of 3 kN in the
x-direction, determine the necessary values of
and T.
