Figure shows a pair of pin jointed gripper tongs holding an object weighing
2000 N. The coefficient of friction
μ at the gripping surface is
0.1.
X−X′ is the line of action of the input force and
Y−Y′ is the line of application of normal gripping force. If the pin-joint is assumed as frictionless, the magnitude of force
F required to hold the weight (in
N) is
