27) I caught me a big shark, one having a mass of 650 kg. It is held up by a strong pole(solid black in the figure) that makes an angle of 55.0° with the horizontal and an attachedcable (light brown in the figure) at its end. The pole is uniform in construction, 4.00 m long,and has a mass of 50.0 kg. The cable makes an angle of 35.0° with the horizontal. Determinethe tension in the cable, and the x and y components of the force exerted at the base of thepole. Start off by drawing the Tension T on the cable and the x and y- forces at the base ofthe pole.35°55°

Step 1: Start by drawing a diagram of all the forces involved.Step 2: Using Newton's Second Law,…

A man holds a 198-N ball in his hand, with the forearm horizontal (see the figure). He can support the ball in this position because of the flexor muscle force M, which is applied perpendicular to the forearm. The forearm weighs 18.5 N and has a center of gravity as indicated. Find (a) the magnitude of M and the (b) magnitude and (c) direction (as a positive angle counterclockwise from horizontal) of the force applied by the upper arm bone to the forearm at the elbow joint.

In the figure below, a uniform beam of weight 420 N and length 2.8 m is suspended horizontally. On the left it is hinged to a wall; on the right is it supported by a cable bolted to the wall at distance D above the beam. The least tension that will snap the cable is 1200 N. Cable Beam (a) What value of D corresponds to that tension? (b) Give any value for D that won't snap the cable. m
A man holds a 195-N ball in his hand, with the forearm horizontal (see the figure).

Problem 5: Fr Fm Bone -Muscle 100 30 cm W 4 cm 40 cm A simplified model of a human arm holding a weight is shown on the right. The length of the forearm is 40 cm and it has a mass of 1.7 kg. The bicep muscle is attached 4 cm in from the elbow joint and makes an angle of 73° with the forearm. The weight in the person's hand has a mass of 5 kg. a) What is the magnitude of the force provided by the bicep muscle needed to keep their arm at rest? b) What is the magnitude and direction of the force acting at the elbow (F;) in that same case?
The forearm shown below is positioned at an angle with respect to the upper arm, and a 5.6 kg mass is held in the hand. The total mass of the forearm and hand is 2.1 kg, and their center of mass is 16.1 cm from the elbow. (Assume the biceps muscle exerts a force on the forearm that acts vertically.) 5.6 kg B 37.5 cm 4.0 cm (a) What is the magnitude of the force (in N) that the biceps muscle exerts on the forearm for 0-60%7 N (b) What is the magnitude of the force on the elbow joint (in N) for the same angle? N (c) How do these forces depend on the angle 07 The force that the biceps muscle exerts increases and the force on the elbow joint decreases as increases. They both decrease as @ increases. They both increase as increases. They do not depend on 0. The force that the biceps muscle exerts decreases and the force on the elbow joint increases as increases.
In a city park a nonuniform wooden beam 4.00 m long is suspended horizontally by a light steel cable at each end. The cable at the left-hand end makes an angle of 30.0° with the vertical and has tension 620 N. The cable at the right-hand end of the beam makes an angle of 50.0° with the vertical. As an employee of the Parks and Recreation Department, you are asked to find the weight of the beam and the location of its center of gravity.
A uniform 22 kg beam, 3.0 m long, is attached to a wall on the left by a hinge, and is supported by a cable on its right end. A 13 kg monkey hangs from the beam, 1.0 m from the left end. a) Determine the tension in the cable. b) Determine the magnitude of the force due to the hinge on the beam.
A block with a mass of m = 1.5 kg rests on a wooden plank. The coefficient of static friction between the block and the plank is μs = 0.44. One end of the board is attached to a hinge so that the other end can be lifted forming an angle, θ, with respect to the ground. Assume the x-axis is along the plank as shown in the figure. a)Assuming the x-direction is along the plank as shown, find an expression for the magnitude of the force of gravity in the y-direction, Fgy, perpendicular to the plank in terms of given quantities and variables available in the palette. b)Write an expression for the magnitude of the maximum friction force along the surface, Fs, in terms of given quantities and variables available in the palette. c)Assuming the static friction is maximized, write an expression, using only the given parameters and variables available in the palette, for the sum of the forces along the plank, ΣFx.
