Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

Crack AB of a slider crack mechanism shown in Figure 2 rotates at a constant speed of 300 rpm in clockwise direction with the length of AB being 0,3 m. The connecting rod BC has a length of 1 m and incline at 45 degrees to vertically positioned piston C. 1.Draw the displacement diagram of the mechanism shown in Figure 2 to scale. 2.Use a vector diagram to determine the velocity of the piston C and connecting rod BC. 3.Calculate the acceleration of piston C and the angular acceleration of connecting rod BC.
