TORQUE APPLICATIONS

 

Real - World Applications:

Torque has numerous applications especially in the physical sciences and engineering. The following hints for homework problems were taken from the physics SP211 web page for 1998. Note the discussion of the concept of torque. You can link to this physics site at USNA Physics SP211.

 

Physics Applications of Torque at USNA, SP211:

Chapter 10 Problem 25

Try this First

 

(a) Draw a free-body diagram of the boom. This is a statics problem. What does the sum of the torques about the pivot point equal?

(b) This is a statics problem. What does the sum of the forces acting on the system equal?

 

Chapter 10 Problem 27

Try this First

 

(a) Determine the relation between Torque, Force, and Moment Arm.

(b) Determine the relation between Torque, angular acceleration, and the moment of inertia.

(c) Determine the relation between angular and tangential acceleration.

 

 

 

More Applications:

 

There are numerous real-world applications of the basic concept of torque. The following includes some industrial applications of interest:

 

  • Tire Testing - Torque sensors utilized in tire development by monitoring torque in the determination of friction of tread design.
  • Vehicle Safety Testing - Wheel torque sensors are designed for use in automotive safety development.
  • Mining Equipment - Equipment design requires a very high torque capacity.
  • Aircraft Engine Design. To quote an aircraft site "Under torque or under tightening results in excessive wear of the hardware as well as the parts being held. Over tightening may cause too much stress on the bolt or nut. The best way to avoid this is to use a torque wrench."
  • Golf Club Design - the following is an excerpt of link headings from a web page by a Golf Club Design firm, Golf Clubs Etc.
  • Torque
  • Is torque a desirable trait in a shaft?
  • Do graphite shafts have more torque than steel shafts?

This complete site, with more details on these topics, can be found at Golf Site.
