Question 1
A cam is a mechanical member used to impart a desired motion to a follower by direct contact. Which one of the under-listed follower motion types will produce the least jerk to the system?
Question 2
Which of the following term defines the size of the cam?
Question 3
The moment of Inertia of an helicopter is 10kg m2 and speed of rotation is 600 rpm clockwise when viewed from front. It turning moment is 1000 N-m, find precession angular velocity in (rad/sec).
Question 4
An aircraft cruising at 360 kmph takes a right turn on an arc of 100 m radius. The turbines and propellers have a total mass of 500 kg with radius of gyration of 25 cm. The engine rotates at 2000 r.p.m. The magnitude of the gyroscopic couple generated is
Question 5
A bike is moving on a curved flat road of radius 200 m with a speed of 25 m/s. The combined moment of inertia of the rotating masses is 16 kg-m2. Consider rotating masses of the engine have an angular speed of 50 rad/s in clockwise direction when viewed from the front of the bike. Find the magnitude of the gyroscopic moment ________.
