Turning Moments

1. How can turning moments be applied in everyday life? It may be advantageous to give worked examples in each case.



2. Can I use wheels & wrenches as examples? Can you please give me more examples?



3. I really don't know what examples I could work from the wheels and wrenches.

Wheels and wrenches would be excellent examples. Others could include see-saws, Ferris wheels, pulleys etc. :smile:

Look around , you will find plenty of examples.Any tool in which point of application of force and the actually point where we need the rotation/turning ...:shy:

How about turbomachinery which drive generators which induce electric currents which drive machines/pumps? Jet engines that power aircraft and piston combustion engines that propel cars, buses, railroad locomotives, boats/ships. How about bicycles? Mechanical clocks and watches.
 
How can I give/do worked examples... in terms of calculations and data?

Pick some questions from your textbook and work through them, or make up your own questions (let your imagination run wild :tongue2: ).
 
I meantlike force applied, distance etc... :(

A mechanic needs to change a tyre on a car. To undo a wheel nut requires 20Nm of torque. If the mechanic has a wrench of length 30cm, how much force must he exert on the end of wrench in order to undo the wheel nut?

[Ladders leaning against walls also make good questions :wink:]
