A wheel tractor has a 200HP engine.If the weight of the wheel tractor is 30 tons and the weight on the drivingwheels is 50% of this weight, and it is operating at an altitute of 1000m above sea level, at an average temperature of 25 degree celcius, and at an average speed of 12km/hr. What is the maximum available rimpull if thecoefficient of traction is 0.25?. Take rimpull efficiency as 85%
A windmill turns a series of slender rods fixed about one end . They are initially 2 meters long, and go at a speed of 15 revolutions per minute. I suggested making the blades 1m long to reduce the cross-sectional area of the windmill, keeping the mass the same for mechanical stress consistency. How fast are the windmill blades going now, in revolutions per minute?
A. A motorcycle and rider have a combined mass of 350kg. The wheels each have a mass of 20kg, diameter of 500mm and radius of gyration of 200mm. The rider accelerates uniformly from 5m/s to 25m/s over a distance of 100m, whilst climbing a hill of slope 1 in 20. The average resistance to motion, including drag, is 105 N. 1. Determine the total work done as the motorcycle ascends the incline. 2. Calculate the amount of power developed during the climb. B. At another point in its journey, the motorcycle and rider travel at 80 km/h around a left-hand bend of radius 30m. Calculate: 1. The angular velocity of each of the wheels. 2. The moment of inertia of each wheel. 3. The magnitude and effect of the gyroscopic torque produced on the bike.
A bicycle rider tries to coast for 300 m to complete one full circuit of a nominally flat oval shaped “track” in an elementary school parking lot on a non-windy day with the air temperature at 20oC. The mass of the rider is 85 kg and the mass of the bike is 12.5 kg. How fast does the initial speed need to be to coast the desired 300 m? Is attaining this speed feasible (i.e., can the rider generate this speed by pedaling on horizontal surface)? Assume: •The rider crouches down a bit to reduce drag (as compared to sitting upright) •The rider cannot maintain balance if the speed gets below 0.1 m/s. •All resistance is due to wind drag
A 24 kg box is being pushed across the floor by a constant force <111, 0, 0> N. The coefficient of kinetic friction for the table and box is 0.18. At t= 8 s the box is at location <16, 5, -6> m, traveling with velocity <3, 0, 0> m/s. What is its position and velocity at t= 9.2 s? What is the new velocity and new position?
Read the question carefully and give me right solution A slender rod with a length of 40 cm and a mass of 2 kg is falling at a rate of 1.5 m/s and at a 35-degree angle as shown below. The rod then strikes a surface and rebounds off it. Assuming that the coefficient of restitution for the impact is .9, and that there is negligible friction between the body and the surface,what is the expected velocity of the center of the rod (C) and the angular velocity immediately after impact?

The consequences of a head-on collision of two automobiles can be studied by considering the impact of the automobile on a barrier, as shown in Fig. 1. Construct a mathematical model by considering the masses of the automobile body, engine, transmission, and suspension and the elasticity of the bumpers, radiator, sheet metal body, driveline, and engine mounts..
A 0.95 kg block connected to light spring with force constant 150 N/m is free to oscillate on a frictionless, horizontal surface. The block is released from rest when the spring is stretched 15.0 cm. What is the speed of the block midway of the stretched position?
Hi, I have the solution for this problem given. However, I don't understand why the Force of Friction is going in the same direction as the displacement by doing positive e work and also why is not considered in the calculations. Here is the problem: A hover board and rider of total mass 80 kg is moving at 1 m/s and encounters a slope of angle 2o. After moving a distance of 10 m up the slope the linear velocity of the hover board is 2 m/s. An electric motor, which is connected to the axle between the two wheels, produces a driving torque acting on the axle. The total moment of inertia of the two wheels, the axle and the motor is 0.02 kgm2. The wheels have a radius of 100 mm. If the wheels, axle and motor rotate through an angle of 100 radians during the motion find the magnitude of driving torque acting on the axle.
What is the maximum power generated by the wind farm with wind speed of 4 m/s? Typical wind turbines have rotor diameters from 40 m to 90 m (Assume increment of 5 m for this problem)-40 m is 80% efficient and efficiency decreases by 5% for every 5 m increase in diameter (i.e. 45 m=75%, 50=70...)-The ridge is 10 km long and wind turbines will be spaced in a single row. •Power in the wind per unit area of circular area is 1/2ρv3W/m2 (v is the wind speed, ρ is 1.3 kg/m3 for air) •Wind turbines cannot be spaced closer than 5 times its diameter without loosing power also there are no partial turbines.
Read the question carefully and give me right solution. A person weighing 160 lb is caught in a tsunami flood water 24 inches deep. Calculate the approximate water speed that would cause them to be ‘swept away’ by the tsunami. Assume that the flood imparts a drag force on each of their legs, and that each leg can be approximated by a smooth circular cylinder with a 6 inch diameter. The person resistance is equal to the normal force times a coefficient friction which can be assumed to be u = 0.5 for rubber sole on concrete. Neglect buoyancy forces.
