Under the action of the force, the rubber cord stretched by 1 cm. What is the value of the force acting on the cord if the stiffness coefficient of the cord is 700 / m.
Initial data: Δl (the amount of deformation of the rubber cord) = 1 cm; k (coefficient of stiffness of the rubber cord) = 700 N / m.
SI system: l = 1 cm = 0.01 m.
The value of the force that acts on the rubber cord is determined from the ratio: F = -Fcont = k * Δl.
Let’s make a calculation: F = 700 * 0.01 = 7 N.
Answer: A force of 7 N acts on the rubber cord.
