You are a consulting biomedical/industrial engineer assisting an employer in a prominent regional manufacturing company. an employee has torn a distal biceps tendon and must undergo rehabilitation. an injury specialist has performed tests and advises that the injured tendon should not be subjected to forces exceeding 650 n during rehabilitation. the employee’s job requires routine handling of parts ranging from 3-6 kg. during manipulation of these parts, the employee must extend the arm with supinated palm and hold the forearm in a horizontal position such that the small angle between the long axis of the upper arm and the forearm ranges from 15°-75°. your task is to perform biostatics analysis to determine if any of these loads causes tendon tension to exceed the value advised by the injury specialist. from this analysis, you will prepare a report for submission to the employer. assume that the axis of rotation of the elbow is fixed at point o and the attachment point of the distal biceps tendon is located at point a, a = 5.7 cm from o. the mass of the entire forearm including hand is mb = 1.66 kg and its center of gravity is located at point b, b = 21.0 cm from o. define the load in the hand as mc; its center of gravity is located at point c, c = 40.6 cm from o. define fm as the biceps tendon tension. assume that the line of action of fm is parallel to the long axis of the upper arm throughout the specified range of motion. therefore, define ? as the angle fm makes with the forearm; i. e., with respect to horizontal. prepare an electronically-generated free-body diagram of the system utilizing the parameters outlined above. you may use shapes in ms word or the drawing program of your choice. include all dimensional information and a coordinate system.2) derive an expression for the magnitude fm in terms of ? and mc. hint: you only need one rotational equilibrium equation to do this.3) compute fm for each of seven masses placed in the hand [mc = 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, and 6.0 kg] at each of seven angles of distal biceps tendon tension [? = 15, 25, 35, 45, 55, 65, and 75°]. prepare a table with these 49 values of distal biceps tendon tension, with ? placed along the x-axis (columns) and mc placed along the y-axis (rows). label and caption this table. highlight values that exceed the limit advised by the injury specialist in a suitable color.4) generate a graph with seven smoothed-line scatter plots (including data points) showing fm (y) vs. ? (x) for each of the seven masses using excel or matlab. draw a heavy line on the graph in a suitable color indicating the tension limit advised by the specialist. likewise, generate a similar graph showing fm (y) vs. mc (x) for each of the seven angles and a line indicating the advised tension limit. label and caption both graphs.
