I think I have found the solution. Have a look Simon. Alright, let me put everything in the right order. Moment is the turning effect of a force around a pivot when the applied force is at right angle with the distance from the pivot, it can found by using the following...

Sorry, it's 65 deg. My bad. Then 25 degree. Does it make sense now?

Hi Simon. Thanks for replying. To cut to the chase, For horizontal positions: M=FXd=-350x0.18=-63 For 60 degree position: M=FXdxsin60=-63xsin60 Am I right? Thanks

Could someone solve this question please? The pedal of a bicycle is 18 cm long. When it is pushed downwards by a cyclist it experiences a force of 350 N. Calculate the moment when the pedal is horizontal and then when it is 65º below the horizontal. Thanks.

Thanks Russ. Does it also mean it is safer ?

Why do they use two different switches, one for the low voltage source and another for the high voltage source, to operate electric motors such as lift machines?
