Chapter 11, Problem 1RQ
Why must safety stands be used after lifting a vehicle with a floor jack?
Expert Solution & Answer
To determine
Why safety stands must be used after lifting a vehicle with a floor jack?
Explanation of Solution
Floor jack is a device used to lift a vehicle or a vehicle component but is not designed for the purpose of holding the load. If the load is retained, the hydraulic fluid in the jack may leak past the seals and lower the component with the possibility of causing a personal injury.
Therefore, safety stands also called jack stands must be used to support the vehicle after lifting the vehicle with the floor jack.

Problem 4
The semicircular disk has a radius of 0.4 m. At one instant, when 0-60°, it is rotating
counterclockwise at 0-4 rad/s, which is increasing in the same direction at 1 rad/s². Find the
velocity and acceleration of point B at this instant. (Suggestion: Set up relative velocity and
relative acceleration that way you would for a no-slip disk; remember what I told you to memorize
on the first day of class.) (Answer: B = −2.98î - 0.8ĵ m/s, ãB = 2.45î - 5.74ĵ m/s²)

- 100 As a spring is heated, its spring constant decreases. Suppose the spring is heated and then cooled so that the spring constant at time t is k(t) = t sin + N/m. If the mass-spring system has mass m = 2 kg and a damping constant b = 1 N-sec/m with initial conditions x(0) = 6 m and x'(0) = -5 m/sec and it is subjected to the harmonic external force f (t) = 100 cos 3t N.
