Question 11 of 25
11. Question
At a point in a piece of stressed material the stresses are as follows:
tensile (normal)
(shearing)
Although the value of (α+β) is not known yet the principal stresses are equal to each other being (5 kN/m^{2}) . What is the radius of Mohr’s circle?Correct
Radius of Mohr’s cycle = 0
Because principle stress are equal to each other being 5 KN per square meter
So r = (55)/2 = 0Incorrect
Radius of Mohr’s cycle = 0
Because principle stress are equal to each other being 5 KN per square meter
So r = (55)/2 = 0

Question 25 of 25
25. Question
In a class of 33 students, 20 play cricket, 25 play football, and 18 play volleyball. Also, 15 play both cricket and football, 12 play football and volleyball, 10 play cricket and volleyball. If each student plays atleast one game, find the number of students who play only cricket.
Correct
Let C, F and V denote the set of number of students who play cricket, football and volleyball respectively. Therefore, n(C) = 20, n(F) = 25, n(V) = 18
Let x represent the students who play all the three games. From above, we get (x – 5) + (x – 4) + (x – 2) + (15 – x) + (12 – x) + (10 – x) + x = 33
x = 7
