Pointers - The scale pointer marks the equal point of the object's mass on the scale and mass on the beam; Zero adjustment knob - This is used to manually adjust the triple beam balance to the 'zero' mark (check to ensure that the pointer is at zero before use). Before using triple beam balance, the scale pointer should be at zero.
The balance (also balance scale, beam balance and laboratory balance) was the first mass measuring instrument invented. [1] In its traditional form, it consists of a pivoted horizontal lever with arms of equal length – the beam or tron – and a weighing pan [10] suspended from each arm (hence the plural name "scales " for a weighing instrument).
The balance beam is a rectangular artistic gymnastics apparatus and an event performed using the apparatus. The apparatus and the event are sometimes simply called "beam". The English abbreviation for the event in gymnastics scoring is BB. The balance beam is performed competitively only by female gymnasts.
A steelyard balance, steelyard, or stilyard is a straight-beam balance with arms of unequal length. It incorporates a counterweight which slides along the longer arm to counterbalance the load and indicate its weight. A steelyard is also known as a Roman steelyard or Roman balance. A 19th-century steelyard crane
A Stewart platform is a type of parallel manipulator that has six prismatic actuators, commonly hydraulic jacks or electric linear actuators, attached in pairs to three positions on the platform's baseplate, crossing over to three mounting points on a top plate.
The significance of the ball and beam system is that it is a simple system which is open-loop unstable. Even if the beam is restricted to be very nearly horizontal, without active feedback, it will swing to one side or the other, and the ball will roll off the end of the beam. To stabilize the ball, a control system which measures the position ...
Beams - The three beams on the balance are used to set the level of precision, with each beam working at different increments (generally 1-10 grams, 10 grams and 100 grams). When using the triple beam balance, it is recommended to start with the lowest level of precision (e.g. 100 gram increments) and then work your way down.
Engine balance refers to how the inertial forces produced by moving parts in an internal combustion engine or steam engine are neutralised with counterweights and balance shafts, to prevent unpleasant and potentially damaging vibration. The strongest inertial forces occur at crankshaft speed (first-order forces) and balance is mandatory, while ...
