Figure shows an arrangement of a carriage system. A force P is applied on the carriage B and moving rightward at 3 m/s2 constant acceleration. At the instant shown the velocity of B is 2 m/s.
(i) Determine the velocity of B relative to A.
(ii) Determine the acceleration of B relative to A
(iii) Determine the absolute velocity of C, Carriage A
(iv) Determine the absolute acceleration of carriage A
(v) Determine the force P and the tension in the rope if mass A= 50 kg and mass B=40 kg (neglect the masses of pulleys, rope and the friction forces at the wheels)
Lawson criterion (J.D. Lawson): A situation for the release of energy from a thermonuclear reactor. Usually it is stated as the minimum value for the product of the density of
What makes a good common end? The capacity to hold the fibers always and flushes, lack of adhesives, absence of packing losses and optical polish.
the numerical ratio of displacement to the distance covered is always ???????????????
Because force=dp/dt and force=0 in first law of motion => dp/dt=0 => p=const. or linear momentum is conserved.
