Tutorial 4: Application of Newton's Laws.The distance between two telephone poles is 50.0 m. When a 1.00 kg bird lands on the telephone wire midway between the poles, the wire sags 0.200 m. Draw a free-body diagram of the bird. How much tension does the bird produce in the wire? Ignore the weight of the wire. [614 N]A 40 kg crate rests on a horizontal floor, and a 75 kg person is standing on the crate. Determine the magnitude of the normal force that (a) the floor exerts on the crate and (b) the crate exerts on the person. [(a) 1.13 x 103 N, (b) 735 N]A worker stands still on a roof sloped at an angle of 45° above the horizontal. He is prevented from slipping by a static frictional force of 450 N. Find the mass of the worker. [85 kg]A 4.0-kg bucket of water is raised from a well by a rope. If the upward acceleration of the bucket is 5.0 m/s2, find the force exerted by the rope on the bucket. [59 N]A block is pressed against a vertical wall by a force, as the drawing shows. This force can either push the block upward at a constant velocity or allow it to slide downward at a constant velocity. The magnitude of the force is different in the two cases, while the directional angle ( is the same. Kinetic friction exists between the block and the wall, and the coefficient of kinetic friction is 0.250. The weight of the block is 39.0 N, and the directional angle for the force is ( = 30.0°. Determine the magnitude of when the block slides (a) up the wall and (b) down the wall. [(a) 52.6 N, (b) 39.4 N]A 3.0 kg block is at rest on a horizontal floor. If you push horizontally on the 3.0 kg block with a force of 12.0 N, it just starts to move. (a) What is the coefficient of static friction? (b) A 7.0 kg block is stacked on top of the 3.0 kg block. What is the magnitude F of the force, acting horizontally on the 3.0 kg block that is required to make the two blocks start to move? [(a) 0.41, (b) 40 N]The systems shown in figure below are in equilibrium. If the spring scales are calibrated in newtons, what do they read? Ignore the masses of the pulleys...

### Quantum Mechanics and its Principals Essay

867 words - 3 pages What is quantum mechanics? Quantum mechanics is the science of things so small that quantum reality has an effect. Quantum means ‘discrete amount or portion’. Max Planck discovered in 1900 that you couldn’t get any smaller than a certain amount of anything. This minimum amount is now called a Planck unit. Niels Bohr, the father of the orthodox ‘Copenhagen Interpretation’ of quantum physics once said, “Anyone who is not shocked by quantum

### The Benefits of Automotive Mechanics Essay

507 words - 2 pages memory recall, working on automotives builds my education. I must learn which tools are useful for each procedure, which develops my problem-solving abilities. Seeing as there are hundreds of parts within an engine, I always have knew information to gather and learn. Since I know that I cannot master auto mechanics in one day, it gives me a kind of homework to study so I can gradually learn more. Also, when troubleshooting, I gain knowledge of what

### Causality, Hume, and Quantum Mechanics

1611 words - 6 pages Causality, Hume, and Quantum Mechanics It is my intention, in the course of this essay, to take the work of David Hume and reapply it to causality using quantum mechanical theory. When I refer to causality, I am referring to the belief that events have a relationship of action "A" causing action "B" where "A" is considered to be the final cause of "B." I also refer to the belief that we can know and understand these causal

### Automotive Mechanics: Automotive Body and Repairmen

1067 words - 4 pages An auto mechanics job is to work on automobiles, A.K.A, vehicles/cars. It is a very important job because; if we didn’t have auto mechanics many peoples’ cars wouldn’t work correctly. Automotive mechanics can be a boy or a girl, and they can work on almost any type of vehicle if they have the right qualifications. Some auto mechanics; like my grandfather, can work on many types of automobiles such as four wheelers, cars, SUV’s, trucks, and

The ratio of the ring and the pinion gear is called the “ final drive ratio or rear axle ration”. The ring gear spins a carrier, which contains perpendicular meshing “ spider gears “ that allow the left and right axle shafts to spin independently (www.popularmechanics.com). The differential spider gears, a term commonly used by mechanics when talking
