Problem 4 A square object is constructed of four identical uniform thin sticks, each of mass m and length L, attached together. This object is hung on a hook at its upper corner. If it is rotated slightly to the right and then released, at what frequency will it swing back and forth? Hints: Find the distance from the hook to the center of mass of the object. Then find the moment of inertia of each stick with respect to...

Change the location of the center of mass to 7cm from the eraser
and change the distance of the center of mass from the pencils lead
tip to be 13.2cm. Finally, assume that the coefficient of friction
0.7. Solve for the minimum angle such that the pencil wont slip.
Enter answer in degrees.

Learning Goal: To be able to find the center of gravity, the center of mass, and the centroid of a composite body. A centroid is an object's geometric center. For an object of uniform composition, its centroid is also its center of mass. Often the centroid of a complex composite body is found by, first, cutting the body into regular shaped segments, and then by calculating the weighted average of the segments' centroids. An object is made from a uniform...

1. An unknown mass (mı) on a rough horizontal surface is attached by a wire that passes over a massless, frictionless pulley to a 2.50kg mass (m2) as shown below. The bottom of the hanging mass is 1.50m above the floor. The system is released from rest at t-0s and the 2.50kg mass strikes the floor 0.82s later. The system is now returned to its initial position and a 1.20kg mass is placed on top of the block of mass...

2. 2/10 points Previous Answers SerPSE10 5.AE.011. My Notes Experimental Determination of H's and The following is a simple method of measuring coefficients of friction. Suppose a block is placed on a rough surface inclined relative to the horizontal as shown in the figure. The incline angle is increased until the block starts to move. Show that you can obtain H by measuring the critical angle e, at which this slipping just occurs. The external forces exerted on a block...

An object of mass m is connected to a light spring with a force constant of kH N/meter which oscillates on a frictionless horizontal surface with Simple Harmonic Motion. At t = 0 the spring was at rest but is compressed x = A meter maximum during oscillation. Write the equation of motion from Newton's 2nd law FH = m·a and Hook's Law FH = -kH·x. Because of the starting position assume a solution is x = A sin(ωt) a...
