Homework Help: Turning Moments

  1. Dec 27, 2006 #1
    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:

    One example could be a simple as opening a jar.

    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: ).

    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:]
