A steel shaft ABCD having a total length of 1.5 m is made of three lengths AB , BC and CD each 0.5 m long. AB and BC are solid shaft having diameter 50 and 75 mm respectively , CD is hollow with outside and inside diameters 75 and 50 mm respectively . when an axial torque of 5 kNm is transmitted from one end of the shaft to the other , the total angle of twist is 1.2° , Determine the maximum shear stress and modulus of rigidity of the material.
- Quiz 1 (20 marks - 10% Weight),
- Quiz 2 (20 marks - 10% Weight),
- Class test (50 marks - 25% Weight),
- Assignment (100 marks - 25% weight) and
- Project (200 marks - 30% weight).
Design a program that will prompt the user for marks for each of the tests and calculate the overall marks (out of 100).
Create a function that will take the array as an argument and return the average of the quizzes.
If I have a 50 liter container that holds 45 moles of gas at a temperature of 472K, what is the pressure
