A uniform horizontal beam 10 m long is attached by a frictionless pivot to a wall. A cable making an angle of 30o (to the beam) is attached to the beam 6 m from the pivot point, supports the beam, which has a mass of 100 kg. The breaking point of the cable is 4000 N. A man of mass 100 kg walks out along the beam. How far can he walk before the cable breaks?

Which statement best explains why an object weight less on mercury than it does on earth

Which of the following bonds would be most polar? a. c-i b. c-br c. c-cl d. c-f e. c-o

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
