Araft is made of 14 logs lashed together. each log is 42 cm in diameter and a length of 6.4 m. 42% of the log volume is above the water when no one is on the raft. determine the following: the specific gravity of the logs.

Explanation:

Given

No of logs

diameter of log

Length of log

42 % of log volume(V) is above water when no one is on raft

so 58 % of log volume(V) is submerged in the water

Weight of 14 log

Buoyancy force on 14 logs

as system is in equilibrium so

Specific gravity of log

the answer would be c. motion and direction

i hope this : )

do you have a formula possibly
