Pulsar Pulsar A pulsar (from "pulse" and "-ar" as in quasar) is a highly magnetized rotating neutron star that emits a beam of electromagnetic radiation. This radiation can be observed only when the beam of emission is pointing toward Earth (much like the way a lighthouse can be seen only when the light is pointed in the direction of an observer), and is responsible for the pulsed appearance of emission. Neutron stars are very dense, and have short, regular rotational periods. This produces a very precise interval between pulses that ranges from milliseconds to seconds for an individual pulsar. Pulsars are
Direct integration of a beam load having an effect on the beam is the 75 kN load applied by the pin, applied at x=0, giving Integrating the internal shear, Assuming an EI value of 1 kNformula_15mformula_15m (for simplicity, real EI values for structural members such as steel are normally greater by powers of ten) Because of the vertical supports at each end of the beam, the displacement (formula_19) at x = 0 and x = 15m is zero. Substituting (x = 0, v(0) = 0) and (x = 15m, v(15m) = 0), we can solve for constants formula_20=-1406.25 and formula_21=0, yielding For the given EI
