A 15,000 N crane pivots around a friction-free axle at its base and is supported by a cable making a 25∘ angle with the crane (Figure 1). The crane is 16 m long and is not uniform, its center of gravity being 7.0 m from the axle as measured along the crane. The cable is attached 3.0 m from the upper end of the crane. When the crane is raised to 55∘ above the horizontal holding an 11,000 N pallet...
2) In the figure below a uniform boom (weight W, = 11,000 N and length L) of a crane is supported by a cable attached of the way from the TOP of the boom. The boom supports & pallet of steel pipes of weight W, = 15,000 N. Here the angle a = 55° and B = 25°. a) Clearly draw all the forces acting on the boom (4 pts). b) Determine the tension in the cable (6 pts) and...
Wire 4) (20 points) A weight W is supported by attaching it to a vertical uniform metal pole by a thing cord passing over a pulley having negligible mass and friction. The cord is attached to the pole 40.0 cm below the top and pulls horizontal on it. The pole is pivoted at a hinge at its base, is 1.60 m tall, and weighs 50.0 N. A thin wire connects the top of the pole to a vertical wire. The...
20.0 I- A 10 000-N shark is supported by a cable attached to a 4.00-m rod that can pivot at its base. Calculate the ten- sion in the tie-rope between the wall and the rod if it is holding the system in the position shown in Figure P12.49. Find the horizontal and vertical forces exerted on the base of the rod. (Neglect the weight of the rod.) where T is the force exerted by the Achilles tendon on the foot...
(non calculus based physics) Question 1 An Olympic weight lifter lifts an 1800 N set of weights from the ground to a vertical distance of 2.20 m above his head. Assuming he moves the weights at constant speed, how much work does the weight lifter do? Question 2 A 4.5 kg trunk, initially at rest, takes 2.0 s to slide 2.8 m down a rough 25° slope. Calculate: the work performed by the force of gravity. the amount of mechanical...
