Question

I solved the tensions in the strings but I'm not quite sure how to appraoch the second half. I have all the data available and I know what static friction is but I'm still stuck.

Any help would be appriciated.

The Figure shows two blocks, block 1 and block 2, held in equilibrium by a massless, unstretchable string. The mass of block 1 is 14.2 kg, the mass of block 2 is 4.6 kg, and the angle theta is 20 degree. What is the tension in each string? The system begins to slip if any additional mass is added to block 2. What is the coefficient of static friction between block 1 and the plane on which it rests? I solved the tensions in the strings but I'm not quite sure how to appraoch the second half. I have all the data available and I know what static friction is but I'm still stuck.

Explanation / Answer

if you have found T1 then

T1 = friction force on block 1

T1 = M1g

= T1/M1g
