A shaft 5.0 cm in diameter and rotating at 2,400 rpm, comes to a full stop in 6.0 seconds. It slows down to 1200 rpm during the first 2.0 seconds and comes to a full stop at the end of the sixth second. The acceleration is constant during both segments of the motion. Determine: a.The total number of turns it completes during the 6.0 seconds it is slowing down, b.the distance traveled by a point on the rim of the shaft during this time, and c.the average acceleration during the first 2.0 seconds in rad/s2.

Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

The 100 meter diameter wheel needs to be designed so that it rotates at a constant rate and every complete revolution takes 15 minutes. The wheel has been installed in a vertical plane and the lowest seat is 2m above the ground surface. Each ride consists of only one full rotation. Find a further general expression for the horizontal displacement of the rider from its initial position with respect to both time and angle of rotation and hence determine the speed of the rider when t= 180 sec. Using calculus, determine what the maximum horizontal and vertical speeds of the rider would be and at which points during the ride they occur. State expressions for the acceleration of the rider in both horizontal and vertical directions and show that the resultant acceleration experienced by the rider is independent of where on the ride he/she might be. In designing a new wheel with the same diameter and same ride duration as before it is proposed that the wheel’s angular speed should not…
