Explain about dead load, live load, impact load, wind load, and snow load.

Explanation of Solution
Dead load: It refers to loads that generally doesn’t change over time, like weights of materials and components of the structure such as flooring material, framing, roofing material and the weights of the service equipment like plumbing, HVAC, etc.
Live loads: It refers to loads that can change over time, like when people walking around a building or movable objects (moving flower pot on a floor).
Impact load: It is the load experienced by a structure when a moving object is suddenly stopped by the structure (hitting or falling one object on another).
Wind load: It is the load applied by speed of the wind and its air density against a building that creates a negative pressure on the leeward side and positive pressure on the windward side. The Eiffel Tower has a structure that was designed to resist a wind load.
Snow load: It is the downward force acting on a building roof due to the weight of the accumulated ice and snow. The entire structure can fail if the snow load exceeds the building weight, due to the poor design structure.
Conclusion:
Hence, the explanation for dead load, live load, impact load, wind load, and snow load are explained.

- Given the truss with loading shown. Note that the roller connection at Joint D is in atrack so that it cannot move in the x-direction, but it can roll in the y-direction.Solve the truss with the virtual load you would use if you are going to solve for the verticaldeflection at Joint E using the method of virtual work.Note: Just solve the truss. You DO NOT need to find the vertical deflection at Joint E.arrow_forwardQuestion (1): (18 Marks) Gaza City has a total population of 650,000 inhabitant, where 75% of the population is connected to wastewater collection system. The water consumption per capita is 100 L/day. Currently, the collected flow treated partially by aerated lagoon system. The municipality intend to change the treatment system to a completely mixed activated sludge system to be used for organic matter removal only to fulfill the Palestinian standards for reuse (Soluble BOD 30 mg/l). The given data from the municipality laboratory and assumptions: ⚫ The influent soluble Biological Oxygen demand = 500 mg/l. Biomass yield (Y) = 0.5 mg VSS/mg BOD removed • Endogenous decay rate constant (Ka) = 0.05d¹ • • The concentration of biomass (X) = 3000 mg MLVSS The concentration of recycled biomass (X) = 10000 mg MLVSS/L Growth rate (d) 2.5 1.25 100 For the completely mixed activated sludge system find the following: a) The average flow to the treatment plant. b) The mean cell residence time. c)…arrow_forwardQuestion (3): (20 Marks) You have been assigned to design a secondary wastewater treatment component based on a tricking filter technique.
