The spool has a mass of 100 kg and a radius of gyration kG = 0.3 m. If the coefficients of static and kinetic friction at A are ms = 0.2 and mk = 0.15, respectively, determine the angular acceleration of the spool if P = 600 N.

LECTURE – 1 MECHANICS Study of what happens to a body when forces are applied to it. Mechanics Rigid bodies Deformable bodies Fluids (Don’t change shape) (Do change shape) Compressible Incompressible Statics Dynamics Fundamental physical Quantities Length Mass Time Force Newton’s second Law relates these quantities through the formula F = ma F = Force applied to object m = mass of object a = acceleration of object 2 different unit systems Standard English
