1. The problem statement, all variables and given/known data
From a toy gun, a bullet of 1N is fired. The bullet travels a distance of 10m. the compression of the spring, when the gun is loaded, is 100 mm and the bore of the barrel is 20mm. design a suitable spring, taking a spring index as 5.5 and design a shear stress for spring material equals to 600N/mm square.
2. Relevant equations
Spring shear stress
3. The attempt at a solution
i am stuck up with the weight and the distance travelled by the bullet. i am stuck up with this staring trouble.please guide me.
