2008年4月22日 · The launcher has to be capable of firing a spring from any angle above the horizontal (0 to 90 degrees) and the target will be at ground level. I think a simple and cheap, but effective design, will be the best for this project.

2007年1月17日 · The launcher consists of a striker connected to the spring... when the spring is pulled back and let go the strike moves forward and hit the projectile. i have the vertical distance of the launch, the mass of both the launcher system (mass of spring + mass of striker), mass of the projectile, the distance the projectile needs to travel and also ...

2015年3月19日 · The deciding criterion is: was the top end of the compressed spring at y=0.48 m or was the top end of the uncompressed spring at 0.48 m (so before the compression). If I'm not mistaken, for the latter case that is a considerable extra compression required.

2013年1月30日 · The launcher and the target is both set on the floor. The spring is the projectile. I will be given the distance on the day of testing. i should take into account air resistance so i will be more accurate. Mass of spring = 0.024kg k = 25N/m launch angle set at 40 degrees length of spring when not stretched is 0.20m height of launcher is 0.54m

2003年12月4日 · Well for a start off your request is an impossibility - you can't transfer ALL of the energy to the ball, only a proportion dependant on the efficiency of the system.

2024年10月24日 · A small spring-loaded launcher is designed to fire steel ball bearings with masses of 0.22 kg. When setting the launcher, you compress the spring a distance of 15 cm. You then fire the launcher straight up and find that the projectiles reach a maximum height of 0.9 m above the point that they leave the launcher.

2009年10月21日 · I decided to make a spring loaded projectile launcher, yet I can't find any material lists or designs on the Internet. The launcher will need to be height and distance adjustable. It needs to be able to be launched within 2-6m, …

2011年1月4日 · A spring is fired from a launcher angled Θ degrees from the floor. The spring has force constant k and mass M. The target is Δd metres away from the launcher and the target is elevated Δy metres. When the spring is launched, it travels at initial speed v0 towards the target, Θ degrees from the horizontal.

2019年6月14日 · The equation for a spring launcher is F = -kx, where F is the force exerted by the spring, k is the spring constant, and x is the displacement from the equilibrium position. How is the spring constant determined? The spring constant is determined by measuring the force exerted by the spring at different displacements and then plotting a graph ...

2008年11月19日 · A spring launcher is a device used to launch objects by utilizing the potential energy stored in a compressed spring. It typically consists of a spring attached to a platform or lever, which is released to launch the object.
