The force pressing the ancient box to the floor, 400 N. To move it, it took 200 N. Determine the static friction coefficient.
Initial data: Fт (force that presses the wooden box to the floor) = 400 N; F (force applied when moving the box) = 200 N.
The coefficient of friction at rest can be determined from the equality: F = Ftr. = μ * N (N is the support reaction force) = μ * Fт, whence μ = F / Fт.
Calculation: μ = 200/400 = 0.5.
Answer: The coefficient of static friction is 0.5.
