siege engine that was employed in the middle ages. It is a modified version of the catapult that uses a counterweight to throw a large stone or blunt object. This means the only power it uses‚ is gravity. This invention brought about the end of knights‚ and castles. It’s usually made out of wood and some other materials‚ so it’s fairly simple to create; which means‚ most if not all societies in the middle ages had one. The trebuchet is often confused with the earlier torsion siege engines. But the

Heat engine lab Intro: when an engine runs‚ it pumps pistons that move up and down and provide energy to the engine to it to go. These pistons move because of pressure and heat. This work done on the system is not only mechanical but its also thermodynamic. When a piston undergoes one full cycle its displacement is zero because it comes back to its resting place. This means that its net thermodynamic work to be done should also be zero‚ as well as its total internal energy. In order to test this

ABSTRACT The quest for an engine which having the same or more power with higher fuel efficiency than the existing ones has started before many years. As a result of all these researches a new engine concept is formed‚ which is a six stroke engine. Lot of research works are conducting on this topic nowadays and already six types of six stroke engines were discovered yet. Of these the resent developed three six stroke engines‚ i.e.‚ Beare head‚ Bruce crowers and Velozeta’s are undergoing tremendous
