Two Boy Scouts, Bobby and Jimmy, are carrying a uniform wooden tent pole 4.80 m in length and having mass        m = 30.0 kg. Bobby is holding the pole 65.0 cm from the back, and Jimmy is holding the pole 37.0 cm from the front. If the pole is held horizontally by the two boys, what is the force Bobby and Jimmy each exert on the beam? (Enter the magnitude.) Fbobby = ________ N Fjimmy = ________ N

As shown below, a beam of length L is in equilibrium and is attached to a cable which is pulling it against a frictionless wall. The beam is not attached to the wall and the wall is only exerting a normal force on the beam. Additionally, there is a 792 N box hanging on a wire from the end of the beam. Determine the cable tension & the beam weight. 0.86 L 45° 792 N tension= beam weight=

Problem: A 80 kg construction worker is sitting 2.0 m from the right end of a 1450 kg, 6.0 m long beam. What is the tension in the cable attached at an angle of 30 deg. from the beam? (A) Pictorial Representation (B) Physical Representation

A hungry bear weighing 735 N walks out on a beam in an attempt to retrieve a basket of goodies hanging at the end of the beam (see the figure below). The beam is uniform, weighs 200 N, and is 5.50 m long, and it is supported by a wire at an angle of e = 60.0°. The basket weighs 80.0 N. Goodies (a) Draw a force diagram for the beam. (Submit a file with a maximum size of 1 MB.) Choose File No file chosen This answer has not been graded yet. (b) When the bear is at x = 1.20 m, find the tension in the wire supporting the beam. When the bear is at x = 1.20 m, find the components of the force exerted by the wall on the left end of the beam. (Assume the positive +x direction is to the right and the positive +y direction is upward. Include the sign of the value in your answer.) F = (c) If the wire can withstand a maximum tension of 875 N, what is the maximum distance the bear can walk before the wire breaks?

Two children push on opposite sides of a door during play. Both push horizontally and perpendicular to the door. One child pushes with a force of 12.5 N at a distance of 0.750 m from the hinges, and the second child pushes at a distance of 0.550 m. What force must the second child exert to keep the door from moving? (assume friction is negligible)

A uniform 34.0-kg beam of length { = 5.95 m is supported by a vertical rope located d = 1.20 m from its left end as in the figure below. The right end of the beam is supported by a vertical column. (a) Find the tension in the rope. (b) Find the force that the column exerts on the right end of the beam. (Enter the magnitude.)

A 30 kg mass is supported at the end of a horizontal beam of negligible mass that is hinged to a pole as shown. A cable at an angle of 42 with the beam helps support the weight. Find the tension in each cable, T1 and T2.

Two children push on opposite sides of a door during play. Both push horizontally and perpendicular to the door. One child pushes with a force of 185 N at a distance of 0.600 m from the hinges, and the second pushes at a distance of 0.400 m. What force (in N) must the second exert to keep the door from moving? Assume friction is negligible.

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?
