Text: ENGINEERING MECHANICS: DYNAMICS Figure 1 shows a mechanism that is typical in power transmission applications. The collar C moves downward with an acceleration (ac) of Y m/s^2. At the instant shown, it has a speed (V) of W m/s, which gives links CB and AB an angular velocity of ωcs. Carefully examine the configuration of the components in the mechanism. Then answer the following leading questions to gain insight into the operation of the mechanism. Figure 1 (a) With the aid of the kinematic diagram, illustrate the velocities V, Vc of point B and C, the angular velocities ωs, ωc of link AB and CB, the angular acceleration ωcs of link AB and CB, the relative position vector rsc and rsa of link AB and CB. Explain what will happen to link AB and CB as the collar C is moving downward and upward. (30 marks) (b) Analyze the angular accelerations of CB and AB as the collar C is moving downward. Use appropriate numerical values for the mechanism speed (Vc), acceleration (ac), the width (a), and height (b) of the mechanism to explain your result. (15 marks) (c) Investigate the angular accelerations of CB and AB as the mechanism speed (V) and acceleration (a) are increased from w to X and Y to z, respectively. Use appropriate numerical values for the mechanism speed (Ve) and acceleration (a.) to explain your result.

Determine the components of the FR hydrostatic force, its module and the FR line of action.
Discuss the role of stimulus duration and intensity on metabolism (ATP production). Your answer should contain all of the metabolic energy systems, their basic characteristics, processes, and substrate utilization—and relate to the duration and intensity of the stimulus. REMEMBER: AS DURATION INCREASES—INTENSITY OF THE STIMULUS MUST DECREASE IN ORDER FOR THE BODY TO SUSTAIN.
