Question

Let a 1 ​ and a 2 ​ be the accelerations of wedges A and B. Let b 1 ​ and b 2 ​ be the accelerations of blocks C and D relative to the wedges A and B respectively, in the directions shown in the figure. Choose the right relation:

TestHub · Accepted Answer

The string joining C and D over the two fixed pulleys has constant length.

Taking the direction of $a_{1}$ as positive, the displacements satisfy

$x_{1} + x_{2} = x_{C} + x_{D}$ ,

so on differentiating twice,

$a_{1} + a_{2} - b_{1} - b_{2} = 0$ .

Option B.
