The rod of the fixed hydraulic cylinder is moving to the left with a constant speed vA = 25 mm/s. Determine the corresponding velocity of slider B when sA = 425 mm. The length of the cord is 1050 mm, and the effects of the radius of the small pulley A may be neglected.

Explanation:

let vertical distance from A to C be  the constraint equation is:

we want to find distance can be written as which we will find by using Pythagorean theorem h 1 is a constant and can be written as h:

taking derivative w.r.t time we get

given which gives us
