The chute is used to divert the flow of water. The flow is 0.4 m /s and it has a cross-sectional area of 0.03 m?. Neglect the weight of the chute and the water on it 4 m Part A Determine the horizontal force acting on the chute at the roller B, necessary for equilibrium. Express your answer to three significant figures and include the appropriate units. Part B Determine the z component of the force acting on the chute at the pin A, necessary for equilibrium. Express your answer to three significant figures and include the appropriate units. Part C Determine the y component of the force acting on the chute at the pin A, necessary for equilibrium. Express your answer to three significant figures and include the appropriate units.

The 100-kg crate is hoisted by the motor M. If the velocity of the crate increases uniformly from 1.5 m/s to 4.5 m/s in 5 s, determine the tension developed in the cable during the motion.

6-7. Water flows through the hose with a velocity of 4 m/s. Determine the force that the water exerts on the wall. Assume the water does not splash back off the wall. 100 mm 4 m/s

15-129. The water flow enters below the hydrant at C at the rate of 0.75 m³/s. It is then divided equally between the two outlets at A and B. If the gauge pressure at Cis 300 kPa, determine the horizontal and vertical force reactions and the moment reaction on the fixed support at C.The diameter of the two outlets at A and B is 75 mm, and the diameter of the inlet pipe at C is 150 mm. The density of water is Pw = 1000 kg/m³. Neglect the mass of the contained water and the hydrant. |250 mm 30°f 650 mm 600 mm

*6-16. The steady jet of water flows from the 100-mm- diameter pipe at 4 m/s. If it strikes the fixed vane and is deflected in the vertical plane as shown, determine the volumetric flow towards A and towards B if the tangen- tial component of the force that the water ex- erts on the vane is zero.

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.

6-79. The jet is flying at 750 km/h. Still air en- ters its engine nacelle at A having a cross- sectional area of 0.8 m2. Fuel is mixed with the air at me 2.5 kg/s and is exhausted with a velocity of 900 m/s, measured relative to the plane. Determine the force the engine exerts on the plane. Take pa = 0.850 kg/m³.

Task 2 The package has a weight of 30 N and slides down the chute. When it reaches the curved portion AB, it is traveling at 2.4 m / s. If the chute is smooth, determine the speed of the package when it reaches the intermediate point C when 0 = 12° and when it reaches the horizontal plane. Also, find the normal force on the package at C. radius = 6 m 450 eMechanica.com -2.4 m/s

5. The jets from both nozzles go out into the atmosphere at a speed of 35p/s. The liquid is water. The axes of the tube and both nozzles lie in a horizontal plane. Determine the forces that the fluid exerts on the support at A to keep the system in that position
