3.Rigid Body Systems. Acceleration: Consider the following diagram that shows three rigid-bodies simply connected by pins. Body AB is rotating about the pin at A and body C is confined to the horizontal slot. At the particular moment show body AB has a constant angular acceleration, au 0.8 rad/s', and an angular velocity. CAB - 4.0 rad/s. It is also known that the speed of pin B is, V8 - 12 m/s, the angular speed of body BC is OBC...

01. Answer both parts of this question. Part-1 2D Rigid Body Dynamics The machine shown in Figure Q1a comprises an arm AB attached to a rotating joint at point A, which can also be elevated by a hydraulic ram. The arm has mass 100 kg and moment of inertia IG = 10 kgm about mass centre G. A fixed x-y frame is shown with its origin at point A. At the instant shown, the arm is in the horizontal position...
4. (Rigid body rotation) A blob is made from four small objects of mass m attached together with massless bars of length l. The angle made by the bars is 45 degrees. A Identify the principle axes for this blob. B Using a coordinate system, the body frame, that corresponds to those axes, determine the intertia tensor for rotation about the center point. C Suppose that the blob is floating in space, with no torques applied, and is rotating with...

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...
