A boat moves through the sea.
There is a 3000 N force to the west on the boat.
There is a 1000 N force to the south on the boat.
Determine the magnitude and direction of the resultant force on the boat.
Draw a vector diagram of these forces to scale

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
