For a short interval of motion, collar A moves alongits fi xed shaft with a velocity vA

Chapter 7, Problem 7/52

(choose chapter or problem)

For a short interval of motion, collar A moves along its fixed shaft with a velocity \(v_{A}=2 \mathrm{~m} / \mathrm{s}\) in the Y-direction. Collar B, in turn, slides along its fixed vertical shaft. Link AB is 700 mm in length and can turn within the clevis at A to allow for the angular change between the clevises. For the instant when A passes the position where y = 200 mm, determine the velocity of collar B using nonrotating axes attached to B and find the component \(\omega_{n}\), normal to AB, of the angular velocity of the link. Also solve for \(v_{B}\) by differentiating the appropriate relation \(x^{2}+y^{2}+z^{2}=l^{2}\).
