Synchronous tie exhibits the typical behaviour that as power transfer is gradually increased a maximum limit is reached beyond which the system cannot stay in synchronism‚ i.e.‚ it falls out of step. 2. The system is basically a spring-inertia oscillatory system with inertia on the mechanical side and spring action provided by the synchronous tie wherein power transfer is proportional to sin d or d (for small d; d being the relative internal angle of machines). 3. Because of power transfer being proportional

Torque:- Torque is the tendency of a force to rotate an object about an axis. Just as a force is a push or a pull‚ a torque can be thought of as a twist to an object. Torque is a measure of the turning force on an object such as a bolt or a flywheel. For example‚ pushing or pulling the handle of a wrench connected to a nut or bolt produces a torque (turning force) that loosens or tightens the nut or bolt. Usually‚ the torque acting on a spinning top is just due to the weight of the top.

polar moment of inertia of an assembly and using the result to predict the periodic time of a trifilar suspension of the assembly. Theory: The moment of inertia of a solid object is obtained by integrating the second moment of mass about a particular axis. The general formula for inertia is: where Ig m k I g = mk 2 = inertia in kg.m2 about the mass centre = mass in kg = radius of gyration about mass centre in m. In order to calculate the inertia of an assembly‚ the local inertia Ig needs

angular velocity and its moment of inertia. Just as a moving object’s inertial mass is a measure of its resistance to linear acceleration‚ a rotating object’s moment of inertia is a measure of its resistance to angular acceleration."2 Factors which effect a rotating object’s moment of inertia are its mass and on the distribution of the objects mass about the axis of rotation. A small object with a mass concentrated very close to its axis of rotation will have a small moment of inertia and it will be fairly

Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences

performed in this investigation demonstrating the influence the 2nd moment of area‚ also known as the second moment of inertia‚ had on the load carrying capacity of the beam. The results from test 1 show that it is possible to deduce the deflection of the beam when loaded with point forces by superposition. Results from test 2 show that the deflection of a beam is influenced greatly by its moment of inertia‚ i.e. with a greater value of inertia there is a smaller deflection. Contents Page Nomenclature
