The pulley shown in fig has MOI 0.5kg m 2 and radius 10 cm. Assuming no friction any where, find the acceleration of 4 kg block
Text Solution
Verified by ExpertsThe correct answer is:
D
4 g cos 45 – T 1 = 4a ……….. (i)
(T 1 – T 2 )R = I α α
or T 1 – T 2 = 
………. (ii)
T 2 – 2g cos 45 = 2a ……. (iii)
Adding (i), (ii) and (iii) 2g cos 45 = 6a + 
or
a =
