A heating system, a lightning, and a motor load circuit of a small warehouse establish an 18-KVA power demand at 0.487 power factor lagging on a 220 V, 60 Hz supply. a) Establish the power triangle for the load. b) Determine the power factor capacitor that must be place in parallel with the load to raise the power factor to 0.865 lagging. c) Determine the change in supply current from the uncompensated to the compensated system d) Determine the power factor capacitor that must be placed in parallel with the load to raise the power factor to unity

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.

The maximum shear stress and maximum flexural stress occur at the same location along a beam subjected to a non-uniform bending load. a)-trune b)- false
