Problem 10-91

The concrete shape is formed by rotating the shaded area about the y axis. Determine the moment of inertia Iy. The specific weight of concrete is g = 150 lb>ft3 .

Step-by-Step Solution:
Step 1 of 3

PY 205 Week 5 Newton’s Law of Universal Gravitation - The force of gravitation exerted on one particle by a second particle is always directed toward the second particle o The total force on one particle is the vector sum of the forces exerted by each of the others - Gravity near the earth’s surface o The force of gravity due to the Earth is the weight of the object  mg = G m(mE) / r^2 where mE is the mass of the Earth o The acceleration of the gravity at Earth’s surface is dependent on mE and rE^2 - Satellites and weightlessness o Satellite motion – if the speed is too high, the satellite will be lost. If the speed is too low, it will return to Earth.
