3. The steel I beam in the drawing has a weight of 8.00 kN and is being lifted at constant velocity. What is the tension in each cable attached to its ends? 70° 70°

F. y M. mg AF FY f.Y Fixle Axis The ladder in the picture has a mass of 39 kilograms and a length 3.4 meters. What is the normal force pushing the ladder up from the floor? This force is labeled Ff v in the picture. FN Assume that the ladder's weight is evenly distributed, so it can be treated as a single force through the middle. If the ladder is at a 70° angle from the ground, what is the torque exerted by the weight (using the floor as the pivot point)? N.m The torque from the ladder must be balanced by the torque caused by the normal force on the wall, labeled Fw in the picture. Calculate this force. Fw = The normal force from the wall must be balanced by the friction force from the floor, labeled Ff y in the picture Determine thn

A beam of length 11 m is supported as shown below. There is a pin in the bottom end of the beam and a mass hanging from the top end of the beam. If the mass of the beam is mb =264 kg, the hanging block has a mass of m1 =81.8 kg, theta = 50.1 degrees, and phi = 35.1 degrees, what is magnitude of the tension in the wire attaching the beam to the ground?

A 4 kg cat sits on a 30 kg, 4 m long beam that is supported by a cable. She sits 0.5 m in from the right, and the cable is supporting the beam at a point 1 m in from the left.  The beam is free to rotate at the hinge.  What is the tension in the cable and horizontal and vertical forces exerted by the hinge?  What direction do the vertical and horizontal forces point?

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=

The drawing shows a uniform horizontal beam attached to a vertical wall by a frictionless hinge and supported from below at an angle 0 = 40° by a brace that is attached to a pin. The beam has a weight of 340 N. Three additional forces keep the beam in equilibrium. The brace applies a force P, and the hinge applies a force with a horizontal component H and a vertical component V. (a) Draw the free- body diagram showing the forces that act on the beam. Find the magnitudes of the forces (b) P, (c) H, and (d) V. Beam Hinge Pin Ꮎ Brace E

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 uniform ladder 5.0 m long rests against a frictionless, vertical wall with its lower end 3.0 m from the wall. The ladder weighs 160 N. The coefficient of static friction between the foot of the ladder and the ground is 0.40. A man weighing 740 N climbs slowly up the ladder. (a) What is the maximum friction force, in Newtons, that the ground can exert on the ladder at its lower end? (b) What is the actual friction force, in Newtons, when the man has climbed 1.0 m along the ladder? (c) How far, in meters, along the ladder can the man climb before the ladder starts to slip?
