how to find spring constant with mass

Then we use x = F/k to find the displacement of a 1.5 kg mass. Whether you need help solving quadratic equations, inspiration for the upcoming science fair or the latest update on a major storm, Sciencing is here to help. These last two limitations are completely unrealistic, but they help you avoid complications resulting from the force of gravity acting on the spring itself and energy loss to friction. You might see this equation in the case where the problem is in determining what is the force pulling on or . Assuming these shock absorbers use springs, each one has to support a mass of at least 250 kilograms, which weighs the following:\r\n\r\nF = mg = (250 kg)(9.8 m/s2) = 2,450 N\r\n\r\nwhere F equals force, m equals the mass of the object, and g equals the acceleration due to gravity, 9.8 meters per second2. How do you calculate how far a spring will stretch? You know that the force due to the weight of the car is given by F = mg, where g = 9.81 m/s2, the acceleration due to gravity on Earth, so you can adjust the Hookes law formula as follows: However, only one quarter of the total mass of the car is resting on any wheel, so the mass per spring is 1800 kg / 4 = 450 kg.

Hookes law is valid as long as the elastic material youre dealing with stays elastic that is, it stays within its elastic limit. If you pull a spring too far, it loses its stretchy ability. Springs with larger spring constants will have smaller displacements than springs with lesser spring constants for the same mass added. Then the applied force is 28N for a 0.7 m displacement. k is the spring constant, in Newtons per meter (N/m),. Compare two mass-spring systems, and experiment with spring constant.
