Neutron star had large magnetic fields, then electromagnetic waves would be emitted. Unbeknown to him, radio astronomer Antony Hewish and his research assistant Jocelyn Bell at Cambridge were shortly to detect radio pulses from stars that are now believed to be highly magnetized, rapidly spinning neutron stars, known as pulsars. In 1965, Antony Hewish and Samuel Okoye discovered "an unusual source of high radio brightness temperature in the Crab Nebula". This source turned out to be the Crab Pulsar that resulted from the great supernova of 1054. In 1967, Iosif Shklovsky examined the X-ray and optical observations of Scorpius X-1 and correctly
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
