A 2000-kg horizontal beam is supported at each end. a, Ask an Expert

Academics

Q1. Assume that loop B (in the Part A figure) has length along. What is the loop integral in Ampère's law? Assume that the top end of the loop is extremely far from the solenoid. So that the field there is assumed to be small and can be ignored.

Q2. A 2000-kg horizontal beam is supported at each end. A 160-kg load rests a quarter of the way from one end if the beam and 120 kg cargo is 1/3 from the other end. What is the vertical force on each of the supports?
