Question

Could someone please help me with P8: "Compute the moment of inertia of the rod rotating around the pivot." and P10: "Write the period of oscillation of the physical pendulum in terms of its physical properties and compute its actual value."

Problem 3: Torque and Periodic Motion Consider a rigid uniform rod of length d2m and mass m-1kg pivoted at one end. The pendulum is initially displaced to one side by a small angle 8 2 and released from rest. Assume that we only have conservative forces acting on the system, i.e. that the rod is only subject to gravity and a normal force from the pivot. pivot P P8) Compute the moment of inertia of the rod rotating around the pivot. Q6) Which of the following statements is FALSE? A. Gravity has a torque with respect to the pivot B. Normal force has a torque with respect to the pivot C. The net torque on the system oscillates F2) Draw the free body diagram of the system P9) Compute the net torque on the rod By exploiting Newton's second law for the angular motion you should get to an equation of the form d20 For small angles the system will behave as a pendulum, i.e. its motion is subject to a small angle approximation where sin θ ~ θ P10) Write the period of oscillation of the physical pendulum in terms of its physical properties and compute its actual value
