Factor this where a = something,
ma = Tcos@ - W - Wcos@
@ = theta
a = 1/m * T cos @ -m1g-m2gcos@
a = 1/m *Tcos@ -g(m1-m2cos@)

12x=429981696
How do i find x without using a calculator? (ie rearranging to solve and only using a calculator to solve)
12x=429981696
x = log12(429981696)
x = log(429981696)/log(12)
x = 8

A pulley has two masses hanging off of it. The pulley itself has Mp as its mass. M1>M2. There is also friction acting upon this pulley. How is friction expressed in a torque equation? What other torques are expressed? what is the moment of inertia?
Tk = Friction torque
I*alpha = MR2*alpha = T1-T2-Tk
I=MR2
