Find moment of inertia of an axis passing through one corner of a square and parallel to the diagonal of square.
Answers
Answer:
moment of inertia of an axis passing through one corner of a square and parallel to the diagonal of square notThe parallel axis theorem states that if the body is made to rotate instead about a new axis z′ which is parallel to the first axis and displaced from it by a distance d, then the moment of inertia I with respect to the new axis is related to Icm by. Explicitly, d is the perpendicular distance between the axes z and z′ .

The teacher tells the class that the highest marks obtained by a student in her class is twice the lowest marks plus 7. The highest score is 87. (Take the lowest score to be l.)
Solution:-
From the question it is given that,
Highest score in the class = 87
Let lowest score be l
= 2 × Lowest score + 7 = Highest score in the class
= (2 × l) + 7 = 87
= 2l + 7 = 87
