Question

A uniform 36.0-kg beam of length = 4.55 m is supported by a vertical rope located d = 1.20 m from its left end as in the figure below. The right end of the beam is supported by a vertical column.

(a) Find the tension in the rope.
 ? N upward

(b) Find the force that the column exerts on the right end of the beam.
 ? N upward

A uniform 36.0-kg beam of length = 4.55 m is supported by a vertical rope located d = 1.20 m from its left end as in the figure below. The right end of the beam is supported by a vertical column. (a) Find the tension in the rope. ? N upward (b) Find the force that the column exerts on the right end of the beam. ? N upward

Explanation / Answer

equating torques about the left end,we get, T*1.2 + N*4.55=36*9.8*2.275=802.62 ............(1) equating forces, N+T =36*9.8 =352.8 so, T=352.8-N substituting in .....(1), and solving for N, we get T=239.6N
