Answer #1

In rotational dynamics , we take into consideration only those components of torques that are along the direction of fixed axis.

Since this is the component that cause the body to rotate , it is necessary for every component of torque to lie in a plane perpendicular to the axis of rotation.

Fundamental equations used are

w = wo + t

w^2 = wo^2 + 2

= wot + 0.5t^2

The dynamics equations of motion for rigid body motion is a plane is given by: ΣF = ma       (translational acceleration) ΣMCM = ICMα   (rotational acceleration) where MCM is the moment about the Center of Mass, ICM is moment of inertia about the Center of Mass, and α is the angular acceleration. Prove that for static or quasi-static analysis, the sum of moments can be taken about any point, as shown below ΣF = 0       (translational equilibrium) ΣMa = 0   (rotational equilibrium)...
