A Uniform 1200 N Beam That Is 3

question 16

Multiple Choice

A uniform 1200 N beam that is 3.50 m long is suspended horizontally by two vertical wires at its ends.A small but dense 550 N weight is placed on the beam 2.00 m from one end,as shown in the figure.The tensions,A and B,in the two wires are:

• A)A = 875 N,B = 875 N
• B)A = 836 N,B = 914 N
• C)A = 8960 N,B = 8190 N
• D)A = 914 N,B = 836 N
• E)A = 8190 N,B = 8960 N
