A pinion with radius \(r_1\), and inertia \(I_1\) is driving a gear with radius \(r_2\) and inertia \(I_2\). Torque \(\tau\) is applied on pinion. The following are free body diagrams of pinion and gear showing important forces (\(F_1\) and \(F_2\)) of interaction. Which of the following relations hold true?

During the development of a product, an entirely new process plan is made based on design logic, examination of geometry and tolerance information. This type of process planning is known as

A gear train is made up of five spur gears as shown in the figure. Gear 2 is driver and gear 6 is driven member. N₂, N₃, N₄, N₅ and N₆ represent number of teeth on gears 2, 3, 4, 5, and 6 respectively. The gear(s) which act(s) as idler(s) is/are

Which of the following statements are TRUE for damped vibrations? P. For a system having critical damping, the value of damping ratio is unity and system does not undergo a vibratory motion. Q. Logarithmic decrement method is used to determine the amount of damping in a physical system. R. In case of damping due to dry friction between moving surfaces resisting force of constant magnitude acts opposite to the relative motion. S. For the case of viscous damping, drag force is directly proportional to the square of relative velocity.

Given that \(a\) and \(b\) are integers and \(a + a^2 b^3\) is odd, which one of the following statements is correct?
