Classical mechanics 2 - by Vlad Vasilescu (W)

An object of mass $m=2\text{ kg}$ is suspended from a dynamometer , which is suspended from an elevator's ceiling . What is the indication of the dynamometer if the elevator ascends with the acceleration $a=1.2 \text{ m/s}^2$ ?

Details and Assumptions :

• A dynamometer or "dyno" for short, is a device for measuring force, torque, or power.

• Consider the gravitational acceleration $g=9.8 \text{ m/s}^2$ .
