Problem 2.1391A sprinkler essentially consists of a pipe AB mounted on a hollow shaft. The water comes in the pipeat O and goes out the nozzles at A and B, causing the pipe to rotate. Assume that the particles of watermove through the pipe at a constant rate relative to the pipe of 5 ft/s and that the pipe AB is rotatingat a constant angular velocity of 250 rpm. In all cases, express the answers using the right-handed andorthogonal component system shown.Determine the acceleration of the water particles when they are at d/2 from 0 (still within thehorizontal portion of the pipe). Let d= 7 in.C

📍 Approach to solving the question: Let's re-evaluate each step carefully to ensure accuracy. Given…

Sweden and Norway are at war over who makes the best pickled herring. You are in charge of a Swedish artillery unit that is trying to shoot at some Norwegians located 1000 meters away at the same height as you are. If we neglect the friction of the air, the cannon ball follows a parabolic trajectory; as you certainly recall from prior courses, a cannon ball travels a distance L = V²sin(2a) 9 where V is the initial velocity, a is the angle of the cannon barrel, and g = 9.8 m/s² is the gravitational acceleration. You realize that you only have two options for how to shoot. Option (I) is to use 1 bag of gun powder, which produces an initial velocity of exactly V₁ = 105 m/s, and to try to set the angle to aI,nominal = 39 degree. Option (II) is to use 2 bags of gun powder, which produces exactly VII = 137 m/s, and to try to set the angle to aII,nominal = 15 degree. If you set the angles exactly to the nominal ones, compute the traveling distances. L₁ = LII = The problem is that the cannon…
Q4. As shown in the image below, the freight cars A and B are approaching each other, and they have a mass of mA = 23 Mg and mB = 15 Mg, respectively. The directions of their initial velocities are shown in the image, and the speeds are VÃ,1 · 2.5 m/s and VB,1 = 2.1 m/s. If the two cars collide and get stuck together, then move with the same velocity, determine their common velocity after the collision. Right is considered the positive direction and negative sign must be included if they move to the left after the collision. Please pay attention: the numbers may change since they are randomized. Your answer must include 3 places after the decimal point, and proper Sl unit. A Your Answer: VA,1 Answer units B VB.1
A motorcycle and rider have a combined mass of 350kg. The vehicle's velocity is 100 km/hr. The rider is to go up a hill incline of 10 meters. The wheels each have a mass of 20 kg and a diameter of 500mm. The wheel design consists of 6 spokes with a mass of 0.5 kg for each spoke. a. Determine the vehicle's velocity at the top of the hill, assuming it was a rolling vehicle with engine being turned off. a. Indicate the vehicle's velocity at each meter through the climb. b. Explain the transfer energy and how this affects the behaviour of the system. At another point in its journey, the motorcycle and rider travel at 80 km/h around a left-hand bend of radius 30m. Calculate: a) The angular velocity of each wheel. b) The moment of inertia of each wheel. c) The angular momentum of the wheel prior to entering the bend. d) The magnitude of the gyroscopic torque produced on the bike as the rider is driving around the bend. What is the effect and why is it important to calculate the gyroscopic…
