Table Clamp Pulley or Bench Pulley
Table clamp pulleys also known as "Bench pulleys" are mountable on the edge of a
table to change the direction of the force applied on an object on the table. In
this way you can use weight hangers an weights with known masses to apply the
Bench pulleys may be mounted on standard force
tables, many simple design tables and inclined plain for experiments related to
the force and friction.
This vertical table clamp pulley consists of a
5-cm plastic pulley mounted on a plastic table clamp with an adjustable hinge. It can be used on lab tables or inclined boards for experiments
involving the resolution of forces, friction, motion, etc. It can clamp onto
surfaces up to 2 cm thick.

the lower mount, you will need to fully remove the screw and the nut on
the opposite side and insert them in the lower holes after lowering the

them on a round force table.
Plastic pulley clamps are very
inexpensive; however, they are not the best choice if you need them for
long term use.
