force against the ground will keep propelling the tumbler forward. The end of this sequence‚ a full‚ is a little different than what has been discussed previously. A full is literally spinning in the air‚ and torque is the main force behind the spin. The angular momentum converts into torque and allows the tumblers body to spin as if spinning on an axis until they land again. A sequence begins much like any singular tumbling action. However it takes more force and power to carry through with a sequence

1. Motors use the effect of forces on current-carrying conductors in magnetic fields Discuss the effect on the magnitude of the force on a current-carrying conductor of variations in: The strength of the magnetic field in which it is located • The magnitude of the force is proportional to the magnetic field strength. Thus‚ an increase in magnetic field strength will cause an increase in the force on the wire and a decrease in magnetic field strength will cause a decrease in force on the

CALCULATING MODULUS OF RIGIDITY Modulus of Rigidity Using the initial length‚ radius‚ measurements of torque and angle of twist‚ it is possible to calculate the Modulus of Rigidity for each specimen. The modulus of rigidity or shear modulus represents the ratio of the shear stress to the shear strain. It is denoted ‘G’. To calculate two separate values of G for each specimen‚ it is possible to use two methods. It is important to determine the polar moment of inertia to be used throughout

INTRODUCTION The most important challenge facing car manufacturers today is to offer vehicles that deliver excellent fuel efficiency and superb performance while maintaining cleaner emissions and driving comfort. This seminar deals with i-VTEC (intelligent-Variable valve Timing and lift Electronic Control) engine technology which is one of the advanced technology in the IC engine. i-VTEC is the new trend in Honda ’s latest large capacity four cylinder petrol engine families. An internal combustion

All these above may be found in the pre-requisite tutorials. © D.J.Dunn 1 1. INTRODUCTION A gear box is a device for converting the speed of a shaft from one speed to another. In the process the torque T is also changed. This can be done

INTRODUCTION Electromagnetic clutches operate electrically‚ but transmit torque mechanically. This is why they used to be referred to as electromechanical clutches. Over the years EM became known as electromagnetic versus electro mechanical‚ referring more about their actuation method versus physical operation. Since the clutches started becoming popular over sixty years ago‚ the variety of applications and clutch designs has increased dramatically
