Improvements 1. The angle of the throwing arm was initially stopping at an angle of 90°, so as soon as the ball was launched gravity pulled it and it fell down, this angle of the throwing arm was adjusted accordingly for proper launch so that the ball went straight…

Introduction

Range : The range is the distance covered by the ball after launch. The maximum range for parabolic path which the ball covers can be obtained at an angle of 45°. The horizontal distance from the point of launch to the point where the ball falls gives the range. 2. Trajectory : It is the path covered the ball, from the catapult after the launch the trajectory of the ball is parabolic. 3. Velocity : The rate of change of displacement is termed as the velocity. For a parabolic path the velocity of ball will be taken as the horizontal and vertical component of velocity at different points. 4. Newton’s three laws are applied in the working of the catapult. The first law states an object continues to remain in its state of rest or motion until and unless an external force is applied. The ball starts motion only after the sling or in our catapult the throwing arm is pressed and released and it stops where the forces due to gravity, air resistance etc. stop the ball. Second law states that force is directly proportion to the acceleration of the body and acceleration is inversely proportional to the mass, increasing the mass of projectile or ball will decrease acceleration and force required will increase. ...

This is achieved by providing solutions for both consumer and commercial applications. Civil engineering is one of the oldest fields in engineering that arose out of the many challenges that humanity experienced in the early days. Civil engineers are concerned with overseeing the construction of tunnels, roads, bridges, airports and many other infrastructures. In the course of their job, civil…

Engineering has over time evolved to be a broad field with very many specializations each concerned with different aspects of human life. Engineering is certainly the link between the theoretical science that man learns and discovers daily and the commercial applications of such discoveries. Great advances in engineering have certainly continued to be the order of the day as man grapples with a…

Experiment 2 There is a slight fall in pressure in the approach section and the static pressure is at a minimum about one pipe diameter before the orifice plate. The pressure of the fluid then rises near the face of the orifice. There is then a sudden fall of pressure as the fluid passes through the orifice, but the minimum pressure is not attained until the vena contracta is reached. Beyond the…

It is estimated that more than one third of the total energy such as natural gas, diesel, and gasoline in the world goes to driving automobiles. Today, auto industries are in the toe-tip of enhancing transition into electrical cars. This is because of several forces that limit growth of the oil industry and automotive businesses. These limiting factors have made engineers implement varieties of…

These, however, largely depends on the source of the plasma. The available electric fields for this process is often externally applied though can also be internally generated as a result of the buildup of charge in the growing film surface or in the film itself. The electric fields (EF) are key to the process being that the transport of the charged particle, that is electrons and ions, between…
