1. Torque Wrench

2. Torque calculation
30cm
pivot
10N
⏆ = F⏊d
⏆ = (10)⏊(.3)
⏆ = 3 Nm

3. Torque calculation 1 ? F ⏊ Sin ⍬ = O/h O = sin ⍬ (h) O = sin 60 (10)
F ⏊ = 8.66 N
⏆ = F⏊d
8.66 N
(.3)
= 2.60 Nm

4. Approaches to Torque Where is the pivot point?
What was the force applied ⏊ to the axis of rotation?
How far from the pivot point was the force applied?
Consider the sign conventions for the torque: Clockwise is NEGATIVE
Counterclockwise is POSITIVE
*do not blame me – I did not make it up!!!!

5. Torque calculation 2 - + F⏊ = 40 cos ⍬ = 40 cos 50 F⏊ = 60N cos ⍬
⏆ = F⏊d = 40N (cos 50) (.2m)
= Nm
⏆ = F⏊d = 60N (cos 50) (.1m)
= Nm
Sum: 3.86 – 5.14 = Nm

6. Torque calculation 3 try this one on your own

7. Torque calculation 3 - + + ⏆ = F⏊d = + 40N 1m F⏊ = 60N sin 40 = +40 Nm
⏆ total = = + 21 Nm
