Homework Statement
Two identical blocks are tied together with a string and placed along the same radius of a turntable that is spinning about its center. The inner block is 3 cm from the center and the outer block is 5 cm from the center. The coefficient of static friction between the turntable and the blocks is µs = 0.77, and the string is taut.
a) What is the maximum angular frequency such that neither block slides?
b) Now suppose that the blocks each have a mass m = 22 g. For the value of w you just found, what is the tension in the string?
Homework Equations
-T + µmg = m*R1*Theta^2
T + µmg = m*R2*Theta^2
The Attempt at a Solution
To get the answer to part a I used the above 2 equations and solved for theta which gave me w = 13.8 rads/sec. So to solve the for tension in the string I thought I could just plug in numbers for one of the equations and solve for T.. the problem is that each equation gives a different answer for T and they are both wrong. What am I doing wrong?
