1. Homework Statement

W engine = 500 kg * 9.81 = 4905 N

sin t = 3/5

## Homework Equations

## The Attempt at a Solution

1. use section AE

ΣM

_{a}= 0

[itex] 3/5 * F

_{cd}*2 - 4905 * 3 = 0 [/itex]

[itex] F = 12262.5 N [/itex]

2. use section EB

ΣM

_{e}= 0

[itex] 3/5 * F

_{cd}*1 - 4905 * 2 = 0 [/itex]

[itex] F = 16350 N [/itex]

why 1 and 2 doesn't result same answer ?
