Gravity Luggage
By admin. Filed in Travel In USA |
A question about physics now … 10 points best answer?
http://i71.photobucket.com/albums/i159/JogaBonito7/DSC00758.jpg A passenger plane puts his luggage of 50 kg mass on a cart, as shown in the picture. It applies a force F on the handle to raise the cases of horizontal position shown. (Take acceleration due to gravity at 10 N / kg) The axis of the wheel acts as a pivot. Calculate the moment of the weight of baggage about this axis. The solution is 50 x 10 x 0.2 which gives you 100, but can someone explain to me why is it multiplied by 0.2 but not 0.4?
Multiply by 0.2 (200 mm) as CENER mass baggage is 200 mm from the pivot. You want to use the center of mass, not the farthest point of it!
