Sep 22, 2022 · A crank used in this way reduces speed and increases force. Most cranks work like this, providing leverage to give extra force. A coffee grinder is another good example: it takes quite a lot of force to power the crushers (burrs) that smash the beans to pieces and the handle of the grinder multiplies the force you apply with your hands. If you ...
5. Transmit Power to Parts of an Engine. A crankshaft mainly functions to transmit power to various parts of the engine system such as valve timing, air conditioning compressor, fuel pump, water pump, alternator, and many others. 6. Motorcycles. A crankshaft is a prominent part of the engine of a motorcycle.

This example is a snapshot at crank angle = 50° where inertia forces oppose the driving force and consequently reduce the torque available at the crankshaft. At other points in the cycle inertia forces aid the driving force and increase the crankshaft torque. In the next section we look at crankshaft torque in more detail.
A Crank and Slider mechanism / linkage, takes rotary motion and coverts it to linear motion. The diagram (below), shows how a piston pushes and pulls the connecting rod, which rotates the crank. This is typical of steam engines. This mechanism is vital in combustion engines and has many other practical applications such as; pumps and ...
In reciprocating pumps or compressors, the purpose of the crankshaft is to convert rotary motion from an electric motor or other prime mover into the reciprocating motion used to reciprocate the piston. The crankshafts start rotating with the starting of the motor. This causes the connecting rod to oscillate, resulting in the to-and-fro motion ...
In this example the C of G of the crank arm is at position R/2. Thus F Ica = m ca ω 2 (R/2) = 2 x (2π) 2 x 0.5 = 39.5 N. We can balance this force by placing a rotating counterbalance mass m B at radius R B diametrically opposed to the crank arm such that m B x R B = m ca x (R/2) giving for this example m B = 1/R B kg.

Apr 30, 2024 · A d.c. motor is set up as shown below. Determine whether the coil will be rotating clockwise or anticlockwise. Answer: Step 1: Draw arrows to show the direction of the magnetic field lines. These will go from the north pole of the magnet to the south pole of the magnet. Step 2: Draw arrows to show the direction the current is flowing in the coils.
