Question

You hold a 500 N barbell 0.5 m above a level floor for 100 s . During this time, the amount of work you do on the barbell is

Answer 1

Answer #1

As diaplacement of the barebell is 0 in this time interval, hence no work is done on the barewell because,

Workdone = Force x Displacement

As displacement is 0, therefore

Workdone = 0

A barbell consists of two small balls, each with mass 500 grams (0.5 kg), at the ends of a very low mass rod of length d= 20 cm (0.2 m). The center of the barbell is mounted on the end of a low mass rigid rod of length b= 0.3 m (see Figure). The apparatus is started in such a way that although the rod rotates clockwise with angular speed 80 rad/s, the barbell maintains its vertical orientation. Your answer...
