PROBLEM 2 Knee Extension - The angular motion of the lower leg about the knee joint, and the forces and torques produced by the muscles crossing the knee joint during knee flexions and extensions have been investigated by a number of researchers utilizing different experimental techniques. One of these techniques is discussed here. Consider the person illustrated in Fig. 10.12. The test subject is sitting on a table, with the back placed against a back rest and the lower legs...
An ACL patient is doing leg extensions to strengthen his quadriceps muscles. With no additional weight added, the patient's lower leg (shank+foot) has a mass of 6.25 kg. The center of mass of the lower leg segment is located 32 cm from the axis of rotation of the knee joint. The leg is flexed 25 degree down from horizontal. The quadriceps muscle acts through the patellar tendon, which inserts 5 cm from the axis of rotation of the knee joint...

We 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...
What product would you except from the following reaction? Identify the reagent that can be used to accomplish the following transformation. How would you accomplish the following transformations?
please help! data is provided and be detailed so i can understand Problem I (40pts) Evans et al. (A-5) examined the effect of velocity on ground reaction forces (GRF) in dogs with lameness from a torn cranial cruciate ligament. The dogs were walked and trotted over a force platform and the GRF recorded (in newtons) during the stance phase. The table contains 22 measurements (see problem 1.xlsx) of force expressed as the mean of five force measurements per dog when...
Figure 1 shows the layout of countershaft used to transmit power to a blower through a pulley drive (4-5). Pulley (driving sheave) 4 has a diameter of 125-mm and pulley (driven sheave) 5 has a diameter of 75 mm. Pulley 5 is mounted vertically below pulley 4 (as shown in the figure). Belt tension on the loose side is 20% of the tension on the tight side. A power of 7.5 kW is transmitted via the gear set (2-3) from...

Read the article, more specifically the abstract, introduction, discussion and conlcusion and summarize those specific sections in a paragraph or two. INTRODUCTION With the increase in recreational and competitive cycling, cyclists are experiencing more overuse inju- ries related to repetitive loading.Both intrinsic and extrinsic factors contribute to injury. Intrinsic fac- tors are inherent to the cyclist and include fitness level as well as anatomical alignment of the lower extremities. Extrinsic factors are generally asso- ciated with factors external to the...
