A tighter gear ratio means that you will be rowing through the gears much quicker leading to better acceleration, but will also hinder your top speed. A longer gear ratio takes advantage of the distance between the gears and you will be able to build up more speed, this is at the cost of acceleration though as it takes longer to get into a ...

Electric motor brakes are a type of brake used to stop and hold loads that are driven by AC or DC motors. Motor brakes are used in various material handling, marine, and packaging applications and include various mounting styles such as NEMA C-Face, foot-mounted, servomotor, small gear motor, metric mount, and industrial caliper brakes.
A braking system must also be reliable because should power fail during high winds, brakes become the last line of defense in preventing a catastrophe. An anemometer signals a change in wind direction which energizes the motor driving the gear ring on the yawing system.
With the new baring gear coupling installed, the mill motor starts up whilst baring is taking place, and the mill load is in motion. The baring gear coupling slides back in a keyway and a limit switch simply stops the baring motor. The self-disengagement clutch is a directionally actuated freewheel clutch.

That the Victoria line was built with the future in mind is no coincidence. After all, the line itself was arguably the first to be built solely for the purpose of relieving capacity issues on the existing transport network – hence Mac Hasting's comments on the subject back in 1969. To not assume that the cycle of overcrowding and improvement would need to be repeated at …
