    What is the Constant Torque Applied in a Simple Piston Engine?

    Indeed that is correct. I realized to calculate the energy in the Rod at any point If i was to use the center of mass I would need its horizontal KE, vertical KE and rotational KE. However, I decided I would use the horizontal KE of the rod at the center of mass, then the rotation around...

    What is the Constant Torque Applied in a Simple Piston Engine?

    I guess I should have been more specific. I meant, is there any work done in moving the mass of the piston back and forth. Not turning the wheel or accelerating the engine, just moving the piston. And as to the other part, Is there a reason why it would be better to use the CM of the rod as...

    What is the Constant Torque Applied in a Simple Piston Engine?

    Ok Here is an image: I also have a question about when I am calculating the rotaitonal KE of the rod. Does it rotate around an axis through its centre, or the axis where it connects to the piston?

    What is the Constant Torque Applied in a Simple Piston Engine?

    Homework Statement Find the constant Torque being applied. We are given a diagram of a piston engine, along with the masses of piston, flywheel and rod connecting the two. I know that the expanding gas in the piston does 4 kJ of work. I know that at the beginning of each rotation the engine...
