Challenge Problems
Push your limits with challenges.
Question 1
A cylindrical object of radius 2m has a uniform body force acting downward at 10 N/m³. Calculate the total body force acting on the cylindrical volume if the height is 4m.
💡 Hint: Use the formula for the volume of a cylinder: V = πr²h.
Question 2
Consider a rotating cylindrical tank with a body force of 5 N/m³ directed radially outward. Discuss how this radial force contributes to stability in cylindrical coordinate systems.
💡 Hint: Think about how forces maintain equilibrium in circular motions.
