Question:
Assume that a 12V permanent magnet DC motor is to be used for moving the robot legs.
It has a stall current of 2 ampere and a no load speed of 3000 r.p.m.
Assumer that the friction at no load spped was so little that it can be neglected .
When the suply is at 11V, the motor is...
For the Electronic Bathroom Scale. The maximum load on a
beam is assumed to be 75kg.
(a) Find the max. deflection by using the Young’s Modulus
E=200,000 N/mm². Is it small? Also see next page for the
dimensions of the beam. Hint: For small deflection, tan phyter » phyter.
