Problem 3.90

The force and couple shown are to be replaced by an equivalent single force. Knowing that P = 2Q, determine the required value of if the line of action of the single equivalent force is to pass through (a) Point A, (b) Point C.

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.
