The lower jaw AB [Purple 1] and the upper jaw-handle AD
[Yellow 2] exert vertical clamping forces on the object at R.
The hand squeezes the upper jaw-handle AD [2] and the
lower handle BC [Orane 4] with forces F. (Member CD [Red 3]
acts as if it is pinned at D, but, in a real vise-grips, its
position is actually adjustable.) The clamping force, R,
depends on the geometry and on the squeezing force F
applied to the handles. Determine the proportionality
between the clamping force, R, and the squeezing force F for

- 56 Clamps like the one shown are commonly used in woodworking applications. This clamp has the dimensions given in the table below the figure, and its jaws are mm thick (in the direction perpendicular to the plane of the picture). a.) The screws of the clamp are adjusted so that there is a uniform pressure of P = 150 kPa being applied to the workpieces by the jaws. Determine the force carried in each screw. Hint: the uniform pressure can be modeled in 2-D as a uniform distributed load with intensity w = Pt (units of N/m) acting over the length of contact between the jaw and the workpiece. b.) Determine the minimum vertical force (parallel to the jaws) required to pull either one of the workpieces out of the clamp jaws. Use a coefficient of static friction between all contacting surfaces of μs = 0.56 and the same clamping pressure given for part (a). 2013 Michael Swanbom A B C a Values for dimensions on the figure are given in the following table.
