Question 104: Laws of Motion

Question

In the arrangement shown in figure a1, a2, a3 and a4 are the accelerations of masses m1, m2, m3 and m4 respectively. Which of the following relation is true for this arrangement?

Accepted Answer

From virtual work done method,
4T $$	imes$$ a
1
+ 2T $$	imes$$ a
2
+ T $$	imes$$ a
3
+ T $$	imes$$ a
4
= 0
$$\Rightarrow$$ 4a
1
+ 2a
2
+ a
3
+ a
4
= 0

Answer

4a1 + 2a2 + a3 + a4 = 0

Answer

a1 + 4a2 + 3a3 + a4 = 0

Answer

a1 + 4a2 + 3a3 + 2a4 = 0

Answer

2a1 + 2a2 + 3a3 + a4 = 0
