The hydraulic cylinder BC exerts on member AB force P directed along line BC.
Knowing that must have 600-N component perpendicular to member AB, determine:
1- The magnitude of the force P.
2- The component along line AB.
Knowing that a- 20°. determine the tension in:
The end o the cabl
attached to the pole AB, which is strengthen by the guy wires
AC and AD. Knowing that une tension in wire AC is 120 lb. determine:
1- The components of the force exerted by this wire on the pole
2- The angle directions(a, ß, force forms with the coordinate axes.
Two forces P and Q are applied as shown. Knowing that the connection is in equilibrium
and that the magnitudes of the forces on rods and B are FA=750 lb and FB = 400 1b,
determine the magnitudes of P and Q
A transmission tower is held by three guy wires attached to pin A and anchored
at B. C and D Knowing that the tower exerts on the pin an upward vertical force of
1800 1b determine the tension in each wire.
Collars A and B are connected by 25 inches long wire and can slide freely on
frictionless rods. If 60 1b force Qis applied to collar B as shown determine the tension in the
wire when x = 9 inches and the corresponding magnitude of the force P required to maintain the
equilibrium of the system.
