It is also known as short-circuit test (because it is the mechanical analogy of a transformer short-circuit test), [1] locked rotor test or stalled torque test. [2] From this test, short-circuit current at normal voltage, power factor on short circuit, total leakage reactance, and starting torque of the motor can be found.
Advanced Placement (AP) Human Geography (also known as AP Human Geo, AP Geography, APHG, AP HuGe, APHug, AP Human, HuGS, AP HuGo, or HGAP) is an Advanced Placement social studies course in human geography for high school, usually freshmen students in the US, culminating in an exam administered by the College Board.

Locked-rotor torque (torque at 100% slip), 75–275% of rated torque Pull-up torque, 65–190% of rated torque. Over a motor's normal load range, the torque's slope is approximately linear or proportional to slip because the value of rotor resistance divided by slip, R r ′ / s {\displaystyle R_{r}'/s} , dominates torque in a linear manner.

Typical rotorcraft blades have a Lock number between 3 and 12, [4] usually approximately 8. [5] The Lock number is typically 8 to 10 for articulated rotors and 5 to 7 for hingeless rotors. [3]: 186 High-stiffness blades may have a Lock number up to 14. [4] Larger blades have a higher mass and more inertia, so tend to have a lower Lock number.
This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic ...
ARB air-locking differential fitted to a Mitsubishi Delica L400 LWB Diff. A locking differential is a mechanical component, commonly used in vehicles, designed to overcome the chief limitation of a standard open differential by essentially "locking" both wheels on an axle together as if on a common shaft.
The problem with this definition is that it does not give the direction of the torque but only the magnitude, and hence it is difficult to use in three-dimensional cases. If the force is perpendicular to the displacement vector r , the moment arm will be equal to the distance to the centre, and torque will be a maximum for the given force.
A torc, also spelled torq or torque, is a large rigid or stiff neck ring in metal, made either as a single piece or from strands twisted together. The great majority are open at the front, although some have hook and ring closures and a few have mortice and tenon locking catches to close them.
