48.7 N @ 70°
ROTATIONAL:
10(7) = 70 CCW
20.1(5)= 101 CW

46(2) = 92 CW
NET = 88 Nm CW

Where to put it:

88 = 45.9 dOnly the part causes torque!
1.91 m = dYou need CCW….so think if it should be 1.91 meters to left or right!
Need : 88 Nm CCW

11(2) = 22.0 CCW
9.19(.5) = 4.6 CW

NET = 53.6 Nm CCW
Need: 53.6 Nm CW

Only the part causes torque!
You need CW….so think if it should be 3.29 meters to left or right!

20.TA TB
205675
Put pivot pt on one of the
forces you don’t know(either one)
ROTATIONAL:
CW = CCW
205(1.5) + 675(2) = TB(3)
307.5 + 1350 = 3TB
553 N = TB
You could move pivot pt to other end to get TB
..or use TRANS like I did
TRANSLATIONAL:
UP = DOWN
TA + 553 = 205 + 675
TA = 327 N
