Oscillations of a Balanced Object

Two identical thin rods, each of mass m and length L, are joined at right angles to form an L-shapedobject. This object is balancedon top of a sharp edge.

f the object is displaced slightly, it oscillates.

Assume that the magnitude of the acceleration due to gravity isg.

Find omega, the frequency of oscillationof the object.Your answer for the frequency maycontain the given variables m andL as well as g.

Answer #1
From the above figureThe two identical thin rods each with massM and length Land the two rods at right angles also.so,the third side x is thehypotenuseThe moment of inertia of the thin rod isAnd for the two rods it isThe center of gravity is balanced at a distanceThe fromula for the frequency in the case of uniform rod withlength L is==this may helps you

    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...

    A small object oscillates back and forth at the bottom of a frictionless hemispherical bowl, as the drawing illustrates. The radius of the bowl is R, and the angle is small enough that the object oscillates in simple harmonic motion. Derive an expression for the angular frequency w of the motion. Express your answer in terms of R and g, the magnitude of the acceleration due to gravity. Hemispherical bowl R

    The following problem requires MATLAB. A pendulum is a rigid object suspended from a frictionless pivot point. If the pendulum is allowed to swing back a and forth with given inertia, we can find the frequency of oscillation with the equation 2pi integral = Squareroot mgL/I where f = frequency. m = mass of the pendulum, g = acceleration due to gravity. L = distance from the pivot point to the center of gravity of the pendulum, and I =...

    Question 16 3.5 pts Students attach a thin strip of metal to a table so that the strip is horizontal in relation to the ground. A section of the strip hangs off the edge of the table. A mass is secured to the end of the hanging section of the strip and is then displaced so that the mass-strip system oscillates, as shown in the figure. Students make various measurements of the net force F exerted on the mass as...
