- B6a) An anemometer for measuring the wind speed consists of three thin, hemispherical shells of mass Meach and three connecting rods of mass mas shown in Figure Q1a. If the mass moment of inertia of the thin hemispherical shell about its centre of mass, axis GG' is given by 12 5 Ma? where a is the inner radius of the hemispherical shell. Find the mass moment of inertia of the anemometer about the axis AA'. Give your answer in terms of M, m, a and I. Consider the central rod as a thin rod. b) If the anemometer is rotating at 4 rev/sec. The system parameters are given as M=200g, m=90 g, a=40 mm and l=0.3m find the rotational kinetic energy and angular momentum. A' GPlease see Part 6C of the attached photo.
- I've done simmlar problems before but I can't figure out how to factor in the top part of the pendulum can you show me what I am missing here?Find the moments of inertia in kg-m2 of the pendulum shown in the figure below about the z-axis. The x and y axes are in the plane of the pendulum. Ris a slender rod of 1.0 kg, and D is a semicircular disk of 2.0 kg. L = 1.1 m and r = 0.25 m. R L D Figure is from "Engineering Mechanic An Introduction to Dynamics", McGill and King.Each problem requires a proper FBD and separate kinematic diagram. 1. We have solved many a problem where the mass of the pulley is negligible. Now, let's consider a pully with significant mass (15 kg) with a radius of gyration of 130 mm. Attached to this pulley are two masses of weights 10 kg and 8 kg. Find the downward accleration of the 10 kg cylinder. Compare your answer to the case where the pulley mass is ignored. When pulley mass is considered, the kinematic laws of pulleys are still usable, however, the tensions on each side of the pulley are no longer equal. r = 250 mm 10 kg 15 kg 8 kg
