smooth engagement of clutch in regular vehicles. Clutches without tortion dampners put more torque to the ground faster for racing applications.

"What is the difference between single plate clutch and multi plate clutch?"
To Remove: 1. Remove or disconnect the following: Transmission Quick disconnect from the slave cylinder 2. Install a clutch alignment tool. 3. Mark the flywheel and a clutch pressure plate lug for the installation alignment if reusing the pressure plate. 4. Remove or disconnect the following: Pressure plate bolts and the washers 5. Secure the clutch pressure plate and the clutch driven plate to the flywheel. 5. Remove the clutch alignment tool. To install: 1. Install or connect the following: Bolts and the washers securing the clutch pressure plate and the clutch driven plate to the flywheel Clutch alignment tool 2. Install the pressure plate. Align the marks made during removal if reusing the pressure plate. Tighten the clutch pressure plate mounting bolts. Torque to: 30 ft. lbs. (40 Nm) on the NV3500 or 33 ft. lbs. (44 Nm) on the NV1500 3. Remove the clutch alignment tool. 4. Install or connect the following: Manual Transmission, Quick disconnect to the concentric slave cylinder 5. Bleed the clutch hydraulic system if necessary. 6. Test drive the vehicle to confirm the repairs.
I need to calculate the stress resulting from a torsion moment on a hollow steel section as well as a flat plate.
At the clutch plate and the pressure plate.
Clutch, yes. Pressure plate, No.
A clutch is that part of engine which engages or disengages power from the engine crankshaft to transmission. A clutch is mechanism by which you change the gears. In simple words, it turns on or off power to rear wheel. A clutch is made of clutch assembly which includes clutch plate, Clutch basket, Clutch hub, pressure plates, Clutch springs, lever and clutch cable.Clutch Basket: It is bowl shaped basket which holds entire clutch assembly. It has teethes on the outside surfaces which fix on the primary drive teethes. It means that it is connected with the transmission. It is bolted onto the end of clutch shaft.Clutch Hub: The clutch hub places between clutch basket and pressure plate. The clutch plates are mounted on it. It has teethes in the centre hole which rotate with main shaft. It means it is connected with the engine.Clutch Plate: There are two types of plates in clutch plate. One is Drive (friction) plate another is Driven (Steel) plateDrive (friction) plate: The friction plate is ring shaped and coated with fiber. It is a wear and tear part of clutch assembly. The friction plate surfaces interface between the clutch basket tangs (gaps) and pressure plate. It has teethes on the outside surfaces. These teethes fix on the cutouts between clutch hub tangs (gaps). It is coated with the same material as you see in brake pad (shoe).Driven (steel) plate: It is ring shaped and made of steel and sometime of aluminum. The surfaces of steel or aluminum plate interfaces between pressure plate and clutch hub. It has teethes on inside surfaces. This teethes are fix on the cutouts of clutch hub. Mostly steel plates are used in clutch assembly due to their durability. The aluminum plates are used in Moto GP due to their lighter weight. These plates are worn out very fast compare to steel plate.Pressure Plate: It is the moving part of the clutch assembly which works against clutch spring tension. It releases the clamping action on the clutch plates when the clutch lever is engaged.Clutch springs: The clutch springs shape is like short coil. These springs continuously hold the friction and steel or aluminum plates through spring tension. It also prevents slippage except when the clutch lever is engaged. Most of motorcycle has five or more springs used per clutch assembly. For higher engine output stiffer or more springs are used while softer or few springs used in order to lighter clutch level pulling effort.Lever: It is metal rode which pivots on a perch located of the left handlebar. It gives input to clutch assembly.Clutch Cable: The clutch cable is a cable through which the rider's input passes to the clutch internals.Clutch Cover: It covers the entire clutch assembly
If its more like a judder, clutch, could be oil or damaged plate.
Broken clutch cable or clutch pressure plate fork.
a pressure plate works by springs. when disengaged the tension is released from the springs which hold the clutch plate against the flywheel,allowing the clutch plate to spin free,which basically stops the transfer of power from engine to gearbox when clutch is engaged the tension is reapplied to springs in pressure plate forcing the clutch plate against the flywheel
The springs around the clutch plate have probably came out and locked up between the pressure plate and the clutch plate and locked them together. you need to change the clutch plate and have the pressure plate checked for damage.
Cheap... A couple hundred bucks if you do it yourself. How long do you need this thing to last? If the clutch is just worn, and you have not driven it much w/ the worn clutch, you might be able to get away with replacing just the clutch disk and throwout bearing while leaving the pressure plate and flywheel for the next owner. If the clutch is blown, meaning the throwout bearing seized, the springs on the pressure plate are toast or you drove it with a slipping clutch for too long, the cost will be more, as the pressure plate adds $100 and machining the flywheel is another 30 - 50$.
