the square jaw clutch can be engaged at any speed?
false
only at very low speeds
true or false
Spiral jaw clutch is a positive contact clutch that can drive in either direction
false
one direction only opposite causes to disengage
Friction clutches can be engaged at any speed to apply a smooth power, transition, true or false
true
Wet friction clutches slept more than dry friction, clutches, true or false
fasle
handles high slip conditions
Friction plate material is softer than pressure plate, material, true or false
true
Multiple disc clutches provide more power transmission without greatly increase in clutch diameters true or false
true
Air can be used as a clutch, engaging, medium true false
true
Central fugal force aids in quick release, time for contracting shoe clutches
true
A clutch disc or clutch plate can be engaged by springs in a pressure plate, mechanical over centre mechanism, or by air bladder or piston true or false
true
Cone clutches, engaged by two tapered hubs wedging together axially true or false
true
smaller the angle better wedging power
The power of engagement on central fugal clutches, depends on the weight of the shoes, the strength of the return Springs and the speed of the prime mover, true or false
true
The output, part of the fluid coupling is the turbine true or false
true
the turbine its the out put
the impeller is the input
The flow in the fluid coupling at start up as high Vortx flow, true or false
true
The torque converter and fluid coupling differ only in that the fluid coupling are more efficient
false
major difference is that the converter has a stator
Disc type brakes have better stoping and holding power than drum brakes true or false
true
