1. The ramp shown below is used to assist passengers boarding
light commuter
aircrafts. The average mass of the ramp and passengers is 800
kg with the center of
mass located at point G. As the ramp angle θ increases, the
hydraulic cylinder
extends but the distance between the center of mass G and pivot
C remains fixed.

a) Derive the equation for length AB as a function of BC, AC
and θ. (1 points)
b) Derive the equation for angle BAC as a function of BC, AB
and θ. (2 points
c) Calculate the pivot reaction force (FC) and hydraulic cylinder
force (FAB) at a
ramp angle of 10 degrees. (4 points)
d) Plot the variation of Fc and FAB as a function of θ over the
range 10 < θ < 20.

3. The pipe clamp ends are designed to fit a standard 20 mm
steel water pipe. The

11. right hand fitting can slide along the pipe when handle C is held
up to release its grip
on the pipe. When the handle is released and a clamping load
of F = 1000 N is
applied by the screw, the fitting makes contact with the pipe at
points A and B. In this
position, the spring is compressed with a spring constant of 400
N/mm. Assume that
the handle is a frictionless surface.(10 points)
a) Determine the static friction coefficient at point B needed to
avoid slip under
loading. (2 points)
b) Calculate the force acting at point A and B under loading. (2
points)
c) Estimate the compression of the spring under loading.
Assume that the
handle OC remains parallel to the pipe. (3 points)
d) Calculate the handle force required to loosen the fitting. (2
points)
e) Calculate the force supported by pin O when the above
handle force is
applied. (1 points)
