For 100% torque transmit by clutch it will designed 150% of torque transmit

Avinash said: (Aug 12, 2013)  
Why the torque is 150 percent?

Why it is designed to transmit more torque?

The components of each and every machine are designed with a "Factor Of Safety". For any component the operating load may vary and even sometimes go beyond its designed load limits.

In general, as you know in case of an automobile they main power transmission component being the clutch, it will be subject to varied extreme loads as well (in case of sudden accelerations). Hence to provide optimum performance and life, it is designed for 150% instead of 100%.

By using clutch only more torque is produced, by changing of transmission rate more torque is varied.

maximum torque need for wheel drive so it is design high torque.

Can anybody give a reference as to why 150%? Why not 125% or 175%?

Yes factor of safety matters in this query and because 150 % we should understand it logically considering the FOS. Instead of 100% or even 175 200 etc.

Kirti said: (Dec 30, 2014)  
While designing weight of component, manufacturing time and life of component are also matters along with (FOS) i.e Factor of Safety, and by calculations every values are considered.

If we take 200% or 175% of course it will require more material due to the strength i.e. more weight. So, by calculations 150 can be acceptable.

How to increase the engine torque by clutch?

Anmol said: (Mar 21, 2015)  
Clutch is not used to provide torque to engine but it is used to step up the torque which is provide by the engine.

Shubham Fawade said: (Sep 7, 2015)  
Its for factor of safety.

Shahid said: (Oct 17, 2015)  
While we change the torque. What else will vary?

Vrushankh said: (Oct 17, 2015)  
It is completely basic physics. Clutch works on the principle of friction. From basic physics we have Torque = Force*Perpendicular distance. And we know that frictional force will increase upon increasing the applied force. So indirectly frictional torque will increase.

If we design a clutch for the required torque then there is a chance of slip. SO, it is designed for the higher friction.

It is designed for transmit 150% torque for design purpose But in actual working it transmit better power.

Dhruv said: (Mar 16, 2017)  
How it is designed to deliver 150% torque?

Explain it.

Ganesh Kumar Kothalanka said: (Jun 3, 2017)  
For any material or design, testing = working X 1.5 times.

Ankush said: (Jan 1, 2018)  
Testing is done 1.5 times max values.

Sanjay Kumar said: (Jan 14, 2018)  
There is no roll of clutch plate in torque up down. It gives only same power trasmit which is given by eng. Torque change by only gears.

Theophilus Zogblah said: (Apr 21, 2018)  
Well, I know that the clutch connects and disconnects the engine torque to and from the transmission system.

So, I think what the engine produces is what the clutch transfers. Unless I can understand that it has some multiplication effect. Am I right?

Sam said: (Jun 5, 2018)  
Because flywheel keeps rotating need less power to transmit already rotating shaft.

Ambhore Suraj said: (Jan 2, 2020)  
Why 150?

Varun said: (Apr 17, 2020)  
How much does engine maximum torque exists?
