Figure 9-50 shows a pair of forceps used to hold a thin plastic rod firmly. If the thumb and finger each squeeze with a force Ft = Ff= 11 0 N, what force do the forceps jaws exert on the plastic rod?
Figure 9-50
Amount of force the jaws of forceps exert on the plastic rod.
Answer to Problem 6P
Solution:34.62 N
Explanation of Solution
Given:
The thumb and finger each squeeze with equal force i.e.
Total length of forceps jaw =
Formula Used: Torque:
Net torque = 0 because system is in equilibrium.
Calculation:
The force is acting perpendicular to the point of rotation,
Conclusion: Amount of force the jaws of forceps exert on the plastic rod = 34.62 N.
