PROBLEMS
1 - A ( 200 N ) weight of the block shown in fig. is
supported by a pin and bracket at ( A ) and by a cable
( BC ). Determine the reaction at ( A ) and the tension
30
in the cable
0.75
2 - The 200-N force produces a torque (moment) of
40 N.m about the axis of the bolt in order to
tighten the hexagonal nut. Find the forces
between the smooth jaws of the wrench and the
nut if contact occurs at the corners A and B of
the hexagon.
3 - The pin at A can support a maximum force of 3.2 KN .
What is the coresponding maximum load L which can
be supported by the bracket ?
4 - A block placed under the head, of the claw hammer as
shown greatly facilitates the extraction of the nail. If
the 200-N pull on the handle is required to pull the nail
calculate the tension T in the nail and the magnitude A
of the force exerted by the hammer head on the block
The contacting surfaces at A are sufficiently rough to
prevent slipping

5 - The ring supports the 1000-N load and is held in
position by the two cables attached to vertical walls
Find the tensions T, and T; by at least two different
ways.
1000 N
6 - The cable from A to B is 6 m long and supports
the 100-kg crate from the small pulley .
Calculate the tension T in the cable.
