Question

Three people are hanging from a 10m long beam as the locations shown. Find the position where the fulcrum must be placed (measured from the left end) to balance the beam and 3 people. The mass of the beam is 10 kg. Also determine the location where a 4^th person (20kg) should hang if the fulcrum was at the location you calculated from the first part of this problem. Three objects are hanging from a 10m long as the locations shown. The beam is hung from the ceiling by two triangular shaped rods. Find the force in each rod necessary to support the beam and masses.

Explanation / Answer

7)

Taking torque about left END

50x3 + 200x10 + 10x5 - 360x X

X = 6.11m

20 kg should hang at fulcrum itself
