Question 127: Laws of Motion

Question

In the arrangement shown in figure a
1
, a
2
, a
3
and a
4
are the accelerations of masses m
1
, m
2
, m
3
and m
4
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

4a
1
+ 2a
2
+ a
3
+ a
4
= 0

Answer

a
1
+ 4a
2
+ 3a
3
+ a
4
= 0

Answer

a
1
+ 4a
2
+ 3a
3
+ 2a
4
= 0

Answer

2a
1
+ 2a
2
+ 3a
3
+ a
4
= 0
