SUMMARY
The calculation of Coulomb friction load torque for a rolling spear on a surface with a Coulomb friction coefficient of 0.1 can be determined using the formula τ = f * r, where τ is the torque, f is the frictional force, and r is the radius of the spear. Given a mass of 1 kg and a radius of 0.1 m, the frictional force can be calculated as f = μ * m * g, where μ is the friction coefficient (0.1), m is the mass (1 kg), and g is the acceleration due to gravity (approximately 9.81 m/s²). Thus, the resulting torque can be computed definitively.
