Part (a) [2 marks]
The angular displacement of the rigid body ranges from
θ = 0° (the vertical as shown in the figure) to θ
= 135° and can be modelled using simple harmonic motion. Assuming a
rate of 20 [reps/min], write down an expression for angular
displacement, θ [rad] as a function of time, t [s]. You may assume
that the motion starts with an angular displacement of 135°.
Hint: The angular displacement, θ can be expressed as...

We wish to determine the moment at the shoulder that is required to perform the arm motion (shoulder abduction) depicted in Figure 3 below. This motion may be modelled with a simple, single- element linkage system as shown in the figure. The shoulder joint is represented by a simple pin support centred at O. The arm and the carried weight are represented as a rigid body consisting of a rod and a cuboid. In the rigid body model, the length...
