Find f0, the magnitude of the upward force on the table due to the leg at (0, 0.

Assuming that the table has 4 legs. the upward force is equal to the downwardd force. the downward force of the table is the weight of the table. so the upward force is also the weight of the table but in opposite direction, so the upward force in on one leg is 1/4 of the weight of the table

312.27

Explanation:

22*2.2*44=21296

then add 22+2.2+44= 68.2

divide the first answer with the second to find 312.27 when rounded off
