   Sep 22, 2022 · Force or speed? Find out more. How do cranks work? Engines that make their power with pistons usually need a way of converting back-and-forth (reciprocating) motion into round-and-round (rotational) motion—a way of driving a wheel, in other words. Most engines use cranks to do this.

   We look firstly at output characteristics of a crankshaft and flywheel under torque load conditions using crank effort diagrams. We then consider balancing of inertial forces and moments generated in the mechanism.

   • The Motor Effect. The motor effect is where a force is exerted on a current-carrying wire due to the presence of a magnetic field. There are a range of practical uses of the motor effect including electric motors and l oudspeakers.
   • The Motor Effect and Fleming’s Left-hand Rule. When a current-carrying wire is placed in a magnetic field, the magnetic field produced by the current in the wire interacts with the external magnetic field.
   • Calculating the Size of the Force. For a current-carrying wire placed in a magnetic field at right angles to the field, the size of the force can be calculated using the following equation
   • Electric Motors. We can use the motor effect to produce rotational motion, using a motor. The motor works as follows: The magnetic field exerts a force on the loop of wire.

   Plane motion of a rigid body. When we examine the motion of the crank arm and connecting rod in a crank mechanism we are dealing with the kinematics of rigid bodies moving in a two dimensional plane. Classic theory approaches this as a combination of a longitudinal translation and a rotation represented in the example below.

   The diagram below shows the essential parts of a slider and crank mechanism. The slider, for example, can be a piston in a cylinder or a linear drive element in a machine. Thus the primary input is either a force applied to the slider or a torque applied to the crank arm.

   What is a crank effort diagram?

   • The plot below, called a crank effort diagram, shows the fluctuating torque generated by the engine at the crankshaft, called the engine torque, over one rotational cycle, derived from first principles shown in a previous tutorial. For simplicity we ignore the effects of inertia forces and moments.

   Why do engines use a crank?

   • Engines that make their power with pistons usually need a way of converting back-and-forth (reciprocating) motion into round-and-round (rotational) motion—a way of driving a wheel, in other words. Most engines use cranks to do this. A crank is simply an off-center connection that provides energy to (or takes energy from) a rotating wheel.

   How does a crank work in a generator?

   • Although you're turning the crank, if you do it for a while you soon get a distinct feeling that you're moving your hand back and forth instead of round-and-round. So the crank is really converting a back-and-forth motion of your hand into rotary motion in the generator. Photo by Robert J. Fluegel courtesy of US Navy and Wikimedia Commons.

   What is X in a crank mechanism?

   • Note the inherent characteristic of a crank mechanism that between θ = 0° and θ = 90° on the forward stroke and between θ = 270° and θ = 360° on the return stroke the slider travels significantly more than 50% of the stroke length. In this expression x is a function of variable θ (the crank angle).
