Earth is not spherical but bulges at the equator. Jupiter bulges more. What is the cause of these bulges?
Does the center of gravity coincide with the fulcrum? Why?
Describe the relationship of center of gravity with equilibrium system
A car is stuck in the mud. A tow truck puls on the car with the arrangement shown in the figure below. The tow cable is under a tension of of 2,620 N and pulis downward and to the left on the pin at
its upper end. The light pin is held in equilibrium by forces exerted by the two bars A and B. Each bar is a strut; that is, each is a bar whose weight is small compared to the forces it exerts and which
exerts forces only through hinge pins at its ends. Each strut exerts a force directed parallel to its length. Determine the force of tension or compression in each strut. Proceed as followrs. Make a guess
as to which way (pushing or pulling) each force acts on the top pin. Draw a free-body diegram of the pin. Use the condition for equilibrium of the pin to translate the free-body diagram into equations.
From the equations calculate the forces exerted by struts A and B. If you obtain a positive answer, you correctly guessed the direction of the force. A negative answer means the direction…

Each ball has cross-sectional area 4.00 cm2 and is so shaped that it has a drag coefficient of 0.600.

Assuming no initial rotation and a flow initially directly straight toward the drain, explain what causes the rotation and which direction it has in the Northern Hemisphere.
