A pipe weighing 14 kg lies on the ground. How much force must be applied to one end of the pipe in order to lift it slightly.
| January 27, 2021 | education
To determine the minimum force required to lift one of the ends of the taken pipe, we use the rule of moments: Fт * l1 = F * l2; m * g * l / 2 = F * l, whence we express: F = m * g / 2.
Variables and constants: m is the mass of the taken pipe (m = 14 kg); g – acceleration due to gravity (g = 9.81 m / s2).
Calculation: F = m * g / 2 = 14 * 9.81 / 2 = 68.67 N.
Answer: A force of at least 68.67 N. must be applied to one of the ends of the taken pipe.
