To derive the equation for the work done in rotational motion, we will follow a systematic approach. 1. Understanding Torque: - Torque (τ) is defined as the product of the force (F) applied at a distance (R) from the axis of rotation. - The equation for torque is given by: τ...
As the tangential velocity varies with the radius, the work had done also will be vary with the radius. It is not easy to sum up this work. The help of moment of momentum theorem is used for this purpose. It states that the torque on the rotor equals the rate of change of moment ...
For small values of θ, sinθ≈θ, so that the linearized equation of the undamped pendulum is θ¨+gLθ=0. Work with this equation and the initial conditions θ(0)=0, θ˙(0)=2. a. Find θ(t) if the length of the pendulum is 8 feet. (Take g=32 ft/s2.) b. What is...
where b¯u1 is the equivalent frictional force of motor/arm, I0 is the transverse moment of inertia for arm at the fixed point B, τ is the torque applied to the arm by the motor. Substituting for T1,T2andFϕ1 at their directions defined in Eqs. (14), (15) and (12) respectiv...
for that fact. Frenkel [1] devised a relativistic classical model for the motion of a spinning electron in which the Lorentz force imparted on it by an external electromagnetic field would then be augmented by a torque on it that was due to the coupling of the magnetic moment to ...
geometric pattern, specific for that particular metal or alloy, and are maintained in that pattern by interatomic forces. When so arranged, the atoms are in their state of minimum energy and tend to remain in that arrangement. Work must be done on the metal (that is, energy must be added...
For example, the equal width equation (1.2)ut−uux−utxx=0ut−uux−utxx=0 was first introduced in [31]. It describes amongst others, nonlinear dispersive waves such as shallow water waves and nonlinear waves in plasmas. Extensive work was done on Equation (1.2) in constructing ...
Your work and problems are excellent. By the way, do you know any college that has a doctorate in Mathematics on line as I have nothing else to do. I have tried hard but found none. Again, your page is interesting and excellent for H.S and college students. Sincerely, Harry Du...
