Length of Bamboo Skewer:
24.90 cm Uncertainty of measurement:
± 0.05 cm Is the centre of mass in the exact centre of the bamboo skewer? Why

Problem: 5
Name:
The positions of point A
on the building and point
B on the antenna have
been measured relative to
the electronic distance
meter (EDM) at O.
Determine the distance
between A and B. (Hint:
Formulate a position
vector directed from A to
B; then determine its
magnitude.)

Answer TWO questions from this section
ENG2012-N
The moment of inertia of a helicopter's rotor is 320kg. m². The rotor starts from rest
and at t = 0, the pilot begins by advancing the throttle so that the torque exerted on
the rotor by the engine (in N.m) is modelled by as a function of time (in seconds) by
T = 250t.
a) How long does it take the rotor to turn ten revolutions?
b) What is the rotor's angular velocity (in RPM) when it has turned ten
revolutions?

Calculate the magnitude of the resultant joint force
at L5/S1 joint for the stoop lift. The
worker has a height of 1.8 meters and a mass of 84
kg. The box has a mass of 30 kg.
- Assume that the back extensor muscles have a line
of action parallel to and 5 cm
posterior (on the back side) to the trunk.
- Assume the hands are at the center of the box.
- Use the following masses and COM locations to
calculate the moment at the L5/S1 joint
- Note: the body masses and COM positions for the
parts of the body are not in kg or cm.
They are % of the whole body mass/% away from L5/
S1 joint. You need to convert these
percentages to kg and cm.
- Only consider the FBD and forces for one arm.
Assume each arm holds 15kg of the box
