    which shows the measured value. Working: When a current flow through the coil‚ it generates a magnetic field which is proportional to the current in case of an ammeter. The deflecting torque is produced by the electromagnetic action of the current in the coil and the magnetic field. The controlling torque is provided by two phosphorous bronze flat coiled helical springs. These springs serve as a flexible connection to the coil conductors. Damping is caused by the eddy current set up in the

    A hockey player impels himself forward by pushing off the ice with a power opposite to the skate sharp edge. Since the contact of the edge with the ice is just about zero‚ this is the main way he can impel himself forward. The figure underneath represents the material science behind this guideline. As the hockey player pushes off with his back leg‚ an opposite power F is applied on the skate by the ice. The part of the power F that focuses forward (toward movement) is the thing that pushes the player

    The engine makes 420 horsepower and 420 pounds-foot torques. The Cherokee is powerful enough to get from zero to sixty miles per hour in 4.7 seconds. The Jeep takes 136 ft. to stop from zero to sixty. The Range Rover Sport is a super 4.2 liter Range Rover with a supercharge. The Sport can go from zero to sixty in 6.82 seconds‚ just two seconds shy of the Cherokee. The supercharge in the engine makes 320 horsepower and 410 pound-foot torque. In the break test‚ the Range Rover stops from zero

    having two propellers in a contra- rotating configuration. Contra-rotating‚ also referred to as coaxial contra-rotating‚ is a technique whereby parts of a mechanism rotate in opposite directions about a common axis‚ usually to minimize the effect of torque. Examples include some aircraft propellers‚ resulting in the maximum power of a single piston or turboprop engine to drive two propellers in opposite rotation. Contra-rotating propellers are also common in some marine transmission systems‚ in particular

    Torque The motor is subject to several kinds of torque. The starting or start-up torque is the amount present when the motor is stationary and power is applied. The pull-up torque is the minimum amount necessary for the motor during the starting sequence. Effects of Low Voltage on Torque A reduced amount of voltage will reduce the amount of torque. This can result in difficulty for start loads. A reduction of voltage to 80 percent would result in a torque value
