The magnitude of a velocity vector is called speed. Suppose that a wind is blowing from the direction N45 W at a speed of 30 km/h. (This means that the direction from which the wind blows is 45° west of the northerly direction.) A pilot is steering a plane in the direction N60°E at an airspeed (speed in still air) of 150 km/h. The true course, or track, of the plane is the direction of the resultant of the velocity vectors of the plane and the wind. The ground speed of the plane is the magnitude of the resultant. Find the true course and the ground speed of the plane. (Round your answers to one decimal place.) true course N7 E ground speed km/h

Motor Load, Torque, and Power Quality Requirement

An electric motor is a gadget that changes electrical energy into mechanical energy over to follow up on a mechanical burden. The weight set on the motor because of this mechanical movement is known as motor load. Appropriately matching the motor burden to the engine is vital to forestall harm to the engine or wasteful and unnecessary expensive activity. Engines perform such undertakings as moving a thing starting with one spot then onto the next, cutting it, changing its shape, etc. The motors might be evaluated as far as a few variables including power yield, voltage, current, and temperature. Harm to an engine might happen when it is worked under over the top engine load contrasted with its appraised limit.
