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 4 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 = 0.74, and the string is taut. a) What is the maximum angular frequency such that neither block slides? I got w= 12.7 which was right b) Now suppose that the blocks each have a mass m = 21 g. For the value of w you just found, what is the tension in the string? T= ?N I am stuck on b) I have 2 eqns: T+[tex]\mu[/tex]mg=mR1w^2 -T+[tex]\mu[/tex]mg=mR2w^2 So I keep getting 17N each time I try. What am i doing wrong? T=mR1w^2-[tex]\mu[/tex]mg =21x.05x12.7^2 - .74x21x9.81 =169.4-152.4= 17N Help Please!
