Suppose you have to pile up uniform bricks to erect an inclined wall by offsetting each brick by a constant fraction ,(1)/(n) , of a brick length l over the beneath. How many bricks can be piled by before the wall collapse ? How high a wall can erect if the size of each bricks is 7.5 cm xx 12.5 cm xx 25 cm and the offset is only (1)/(10) of the length of each bricks? What is the total offset you get ? [Hints: The vertical line through CG of the wall must pass through the base. The moment it goes beyond the base brick, the wall will collapse.]

1.	Suppose you have to pile up uniform bricks to erect an inclined wall by offsetting each brick by a constant fraction ,(1)/(n) , of a brick length l over the beneath. How many bricks can be piled by before the wall collapse ? How high a wall can erect if the size of each bricks is 7.5 cm xx 12.5 cm xx 25 cm and the offset is only (1)/(10) of the length of each bricks? What is the total offset you get ? [Hints: The vertical line through CG of the wall must pass through the base. The moment it goes beyond the base brick, the wall will collapse.]
Answer» Answer :(n+1) bricks including the LOWEST one,82.5cm HIGH WALL can be erected , off-set =25 CM
