Aconcrete box culvert with manning’s roughness coefficient n = 0.015 and a rounded entrance (ke = 0.2) is to be designed to carry the design flow of 9.8 m3 /s. the culvert slope is 0.3% and the length is 38.0 m. if the maximum-allowable headwater level is 2.8 m above the culvert invert, determine the size of the box culvert with free-outlet conditions and verify the flow type

What precautions should you take to prevent injuries when dealing with heavy loads?

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
