The two pulleys are riveted together to form a single rigid unit, and each of the two cables is securely wrapped around its respective pulley. If point A on the hoisting cable has a velocity v=0.9 m/s, determine the magnitudes of the velocity of point O and the velocity of point B on the larger pulley for the postion

A 1.6-m wide rectangular channel carries 1.8 m3/s at a depth of 0.85 m. The channel undergoes a smooth transition in which the channel bottom rises 15 cm and contracts to a width of 1.3 m. Assuming friction losses are negligible, determine the dep..
The variation in the diffusion coefficient with temperature, over an appropriate range of temperature, can usually be approximated as follows: D= (D0)e^-(Q/(KT) where, Q = activation energy (eV/atom) and k = Boltzmann's constant (8.616*10-5 eV/ato..
We have a good sense of the fact the increased accuracy comes at a very increased price. Discuss 2 elements of an expensive GPS REC in relation to an inexpensive GPS REC.
