: Water Flow into horizontal pipe with velocity of v. Determine the horizontal and vertical component of force and the moment at A need to hold the elbow in place. Neglected the weight of the elbow and the water within it . Take v between 1 to 5 m/s and D1 between 0.2 to 1.0 m and D2 between 1.0 to 0.2 m. 3 m D1 v1 A В

The block has a mass of 50 kg and rests on the surface of the cart having a mass of 75 kg. If the spring which is attached to the cart and not the block is compressed 0.2 m and the system is released from rest, determine the speed of the block with respect to the cart after the springg becomes undeformed. Neglect the mass of the wheels and the spring in the calculation. Also the neglect friction. Take k = 300N/m,

A toy car is propelled by water that squirts from an internal tank at a constant 6 ft/s relative to the car. The weight of the empty car is 0.4 lb and it holds 2 lb of water. Neglecting other tangential forces, determine the top speed of the car.

The 12-Mg "jump jet" is capable of taking off vertically from the deck of a ship. If its jets exert a constant vertical force of 150 kN on the plane, determine its velocity and how high it goes in t = 6 s, starting from rest. Neglect the loss of fuel during the lift. t.

A plow located on the front of a locomotive scoops up snow at the rate of 10 ft^3/s and stores it in the train. If the locomotive is traveling at a constant speed of 12 ft/s, determine the resistance to motion caused by the shoveling. The specific weight of snow is gs = 6 lb/ft^3

The elevator E and its freight have a total mass of 400kg. Hoisting is provided by the motor M and the 150-kg block C. If the motor has an efficiency of ε =0.85, determine the power that must be supplied to themotor when the elevator is hoisted upwards at aconstant speed of VE = 4 m/s.   Please show every single step of the process and the free body diagrams thanks

The roller coaster car has a mass of 900 kg, including its passenger. It starts from the top of the hill A with a speed VA = 4.1 m/s. Neglect friction, the mass of the wheels, and the size of the car. Take på = 7.5 m and pc = 5 m. (Figure 1) Figure 15 m B 10 m 1 of 1 Part A Determine the minimum height h of the hill crest so that the car travels around the inside loops without leaving the track.

The constant 8-N force is pulling the 2-kg crate across the horizontal surface. If the coefficient of kinetic friction between the crate and the surfce is 0.3, determine the time required to increase the speed v of the crate from 3 m/s to 12 m/s. 8 N 30° 2 kg He =0.3

A vertical take-off and landing aircraft has a mass of 9000 kg. A constant upward thrust of 100 kN is applied to it. Determine the vertical distance it will travel when it reaches the velocity of 10 m/s. Clearly write down here what principle or law you use in this problem. Draw FBD of the aircraft here.
