W engine = 500 kg * 9.81 = 4905 N
sin t = 3/5
Homework Equations
The Attempt at a Solution
1. use section AE
ΣMa = 0
[itex] 3/5 * Fcd *2 - 4905 * 3 = 0 [/itex]
[itex] F = 12262.5 N [/itex]
2. use section EB
ΣMe = 0
[itex] 3/5 * Fcd *1 - 4905 * 2 = 0 [/itex]
[itex] F = 16350 N [/itex]
why 1 and 2 doesn't result same answer ?
