A crate weighs 530 lb and is hung by three ropes attached to
a steel ring at A such that the top surface is parallel to the
xy plane. Point A is located at a height of h = 42 in above
the top of the crate directly over the geometric center of the
top surface. Use the dimensions given in the table below to
determine the tension in each of the three ropes.

The airplane weighs 144100 lbs and flies at constant speed
and trajectory given by 0 on the figure. The plane
experiences a drag force of 73620 lbs.
a.) If = 11.3°, determine the thrust and lift forces
required to maintain this speed and trajectory.
b.) Next consider the case where is unknown, but it is
known that the lift force is equal to 7.8 times the quantity
(Fthrust Fdrag). Compute the resulting trajectory angle
-
and the lift force in this case. Use the same values for the
weight and drag forces as you used for part a.

The hoist consists of a single rope and an arrangement of
frictionless pulleys as shown. If the angle 0 = 59°, determine
the force that must be applied to the rope, Frope, to lift a
load of 4.4 kN. The three-pulley and hook assembly at the
center of the system has a mass of 22.5 kg with a center of
mass that lies on the line of action of the force applied to the
hook.
