Mechanical advantage is defined as the ratio of the force produced by a machine to the force applied to it.
Here, Mechanical advantage is = 0.025/0.50=0.05 .
The moment arm for a muscle force (motive in this case) is 0.025 m, and the...
The triceps muscle in the back of the upper arm extends the forearm. This muscle in a professional boxer exerts a force of 2967 N with an effective perpendicular lever arm of 3.70 cm, producing an angular acceleration of the forearm of 110.0 rad /s'. What is the moment of inertia of the boxer's forearm? moment of inertia: kg-m? Question Credit: OpenStax College Physics
Dan's biceps muscle has a moment arm about the elbow joint of 0.011 m when the joint is held at a joint angle of 90 degrees and can produce a force of 526 N. His forearm is 0.24 m from the elbow joint center to the center of his hand where he grips a handle. His forearm has a mass of 1.2 kg and the center of mass is located directly above the elbow joint. How much force can he...
The triceps muscle in the back of the upper arm extends the forearm. This muscle in a professional boxer exerts a force of 2.00 ✕ 103 N with an effective perpendicular lever arm of 5.00 cm, producing an angular acceleration of the forearm of 105 rad/s2. What is the moment of inertia (in kg·m2) of the boxer's forearm? kg·m2
Help! Thanks! The triceps muscle in the back of the upper arm extends the forearm. This muscle in a professional boxer exerts a force of 2007 N with an effective perpendicular lever arm of 2.05 cm, producing an angular acceleration of the forearm of 115.0 rad/s^2. What is the moment of inertia of the boxer's forearm?
this is actuallu biomechanics. Activity 1: Moment arm and torque (6 pts) 1. What force is required to balance the seesaw in the following figure? 2. What force is required to balance the following seesaw? 80N 6.15k 12NM 5m -1500NM 15cm T: fx D 488- Fr 1 1.3s00 3m SM 1-297e Nm 500N 3. A force of 250 N is applied to a door 0.5 m from the hinge at an angle of 30° as shown, (1) What is the...
BPK201 In the figure to the right, ? is " the force generated by the tendon that flexes the distal finger joint. ? is the external #$" force acting on the finger tip. The position vectors of the point of force application of these two forces relative to the joint center of rotation, c, is illustrated within the dotted box. Calculate the effective mechanical advantage of the tendon relative to the external force. Is this mechanical advantage better suited for...
When you hold your arm outstretched, it's supported primarily by the deltoid muscle. The given figure shows a case in which the deltoid exerts a 67 N force at 15 degrees to the horizontal. If the force-application point is 18 cm horizontally from the shoulder joint, what torque does the deltoid exert about the shoulder?
#1 The elbow joint is flexed using the biceps brachii muscle, which remains essentially vertical as the arm moves in the vertical plane. If this muscle is located a distance a from the pivot point A on the humerus, determine the variation of the moment capacity about A if the constant force developed by the muscle is F. Plot these results of M vs. θ for-60 < θ < 80
A load of 10 kg is held in one hand, with the lower arm horizontal. The lower arm has mass 1.5 kg The distance from the elbow to the hand is 30 cm and the COM can be assumed to be 40% of this distance (from E to H). a) What is the external static elbow moment? (31.2 Nm) b) If the biceps muscle acts with a perpendicular moment arm of 5cm, what force must it generate in order to...
The arm in the figure below weighs 36.0 N. The force of gravity acting on the arm acts through point A. Determine the magnitudes of the tension force F, in the deltoid muscle and the force F exerted by the shoulder on the humerus (upper-arm bone) to hold the arm in the position shown. (Enter your answers to at least the nearest newton.) x Your response is within 10% of the correct value. This may be due to roundoff error,...
