Using constraint method find the relation between acceleration of 1 and 2. |
|
Answer» Solution :At any instant of time LET ` x_ and x_2 ` be the displacement of 1 and 2 from a FIXED line Thenm ` x_1 + x_2 `= constant ` or x_1 + x_2 = l` ( length of string ) Differentiating with respect to time , we have ` v_1 + v_2 = 0 or v_1= -v_2` Again differentiating with respect to time , we get ` a_1 + a_2 =0` ` or a_1 = -a_2` This is the required relation between `a_1` and `a_2` , i.e., ACCELERATION of 1 and 2 are equal but in opposite DIRECTIONS . , |
