A double riveted lap joint is made between 15mm thick plates. The rivet diameter and pitch are 25 mm and 75 mm, respectively. If the ultimate stresses are 400 MPa in tension, 320 MPa in shear and 640 MPa in crushing, find the minimum force per pitch which will rupture the joint. If the above joint is subjected to a load such that the factor of safety is 4, find out the actual stresses developed in the plates and rivets.
A plate 60 mm wide and 12.5 mm thick is to be welded to another plate by means of parallel fillet welds. The plates are subjected to a load of 80 kN. Find the length of the weld. Assume allowable shear strength to be 60 MPa.
Write a programme to demonstrate Hybrid Inheritance with some real examples. Also mention the possible ways of removing ambiguity in this Inheritance.
What is the application of Function overloading and Function Overriding? How do we achieve this? Write programme to demonstrate the use of both features.
There is an Admission class that assigns the admission id and registration number to the Student. The student’s general information i.e. name, email, and contact number is initialized through another class. The student's result is controlled by another class that returns the student's cgpa based on his/her score in all tgpa’s.
Create 5 objects of students, input and display their name, registration number, section, cgpa using any possible type of Inheritance.
Analyze the three chemical equation below then answer th3 corresponding guide question
2N2O(g) → 2N2(g) + O2(g)
SO2Cl2(g) → SO2(g) + Cl2(g)
O + H2 O → 2OH
Guide questions
1. How will you describe the three chemical equations?
2. What can you say about the reactants of the three chemical equations?
3. What type of chemical reaction is displayed by the three chemical equations?
Write the thermochemical equation for the following reactions that occur at constant pressure.
1. Combustion of hexane, C6H12 to carbon dioxide gas and water, releases 3923.9kJ of heat.
2. Reaction between solid phosphorous, P4 and oxygen gas, produces P306 and 1640.1kJ of heat.
3. One mole ammonium nitrate (NH4NO3) dissolves in water to produce aqueous ammonium ions and nitrate ions accompanied by the absorption of 28.1 kJ of heat.
4. Formation of carbon dioxide gas from carbon (graphite) and oxygen yields 393.5 kJ of heat.
Salt is often used to melt ice and snow on roads in the winter and the temperature right now is -4.500°C. How much NaCl (complete dissociation) would be necessary to melt 1000kg of ice by bringing down the freezing temperature to -4.500°C?
Critically compare the main features of ‘Scientific Management Theory’ and ‘Administrative Theory’ of Employment Relations? Discuss how their features contribute to the Unitary Theory of Employment Relations. Also discuss their similarities and differences. Give examples from any overseas country to support each of your main points
So, I have a question on my homework that I have 0 idea how to do it, do you think you could tell me how to do it and give me the answer so I am prepared for future similar questions? Thank you, here is the question:
What mass of Al(OH)2 is required to make 15.6 L of a solution with a pH of 10.72?
