Problem 37P

(III) Four bricks are to be stacked at the edge of a table, each brick overhanging the one below it, so that the top brick extends as far as possible beyond the edge of the table.  To achieve this, show that successive bricks must extend no more than (starting at the top) , and  of their length beyond the one below (Fig.  Is the top brick completely beyond the base? (  ) Determine a general formula for the maximum total distance spanned by  bricks if they are to remain stable.  A builder wants to construct a corbeled arch (Fig.  based on the principle of stability discussed in  and  above. What minimum number of bricks, each  long, is needed if the arch is to span  ?

Step-by-step solution

Step 1 of 7 ^

In order for the first brick to stay on the second brick, the center of mass of the first brick must be just over the edge of the second brick. So the torque of the G1 is zero around the edge of the second brick.
