How do I calculate beam reactions for a simply supported beam?
Sum moments about one support to find the other reaction, then sum vertical forces to find the first. A 10 kN point load at the centre of a 4 m beam gives 5 kN at each support.
What is the formula for torque?
Torque equals force times perpendicular distance from the pivot. A 50 N force applied 0.3 m from the axis produces 15 newton-metres of torque.
What is the difference between torque and moment?
Both are force times distance and use the same units. Torque usually refers to a twisting force on a shaft, while moment refers to a bending or rotating effect on a beam or structure.
What is the Nyquist frequency in DSP?
Nyquist frequency equals half the sampling rate. To capture a signal up to 20 kHz without aliasing, you need a sampling rate of at least 40 kHz, which is why CD audio uses 44.1 kHz.
How do I calculate the moment about a pivot point?
Multiply each force by its perpendicular distance from the pivot, then sum (counterclockwise positive, clockwise negative). A 100 N force 0.5 m to the right gives a clockwise moment of 50 newton-metres.
