A rod of length 1 m is pivoted at its centre. Two masses of 5 kg and 2 kg hang from its ends as shown in the figure. The rod itself has a mass of 1 kg distributed uniformly along its length, and it is initially horizontal. (a) Find the initial angular acceleration of the rod. (b) Find the tension in the supports to the 2 kg and 5 kg blocks.

Options

  1. A= 8.0 rad/s ^2 , T_ 2 kg = 27.6 N , T_ 5 kg = 29 N
  2. B= 6.5 rad/s ^2 , T_ 2 kg = 24 N , T_ 5 kg = 26 N
  3. C= 10.0 rad/s ^2 , T_ 2 kg = 30 N , T_ 5 kg = 32 N
  4. D= 8.0 rad/s ^2 , T_ 2 kg = 29 N , T_ 5 kg = 27.6 N

Correct answer

A. = 8.0 rad/s ^2 , T_ 2 kg = 27.6 N , T_ 5 kg = 29 N

Step-by-step solution

8.0 rad/s ^2 , 27.6 N , 29 N
