Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

Question

Mechanical Engineering

Answer only number 1.

B. Solve the following problems.
1. It took a constant 500 W power to run an engine from rest to its operating speed in 20 seconds. What is the operating
speed of the rotating engine if its moment of inertia is 0.2 kg-m2?
2. You apply a constant torque of 100 Nm to tighten a bolt. If it took 10 revolutions for the bolt to tighten up, how much
work did you do?
3. An electric motor consumes 9.00 kJ of electrical energy in 1.00 min. If one-third of this energy goes into heat and other
forms of internal energy of the motor, with the rest going to the motor output, how much torque will this engine develop if
you run it at 250 rpm?

Branch of science that deals with the stationary and moving bodies under the influence of forces.
