The circular-arc hydrofoil of problem (26) is placed at an angle of attack α= 0 degrees in a uniform water stream at 20o c. take u∞= 5 m/s and p∞= 120 kpa. determine:
(a) the lift coefficient, cl.
(b) the lift l per unit span length.
(c) the velocity magnitude and pressure at the points q1 and p1, where the hydrofoil intersects the y−axis. compare these values to u∞ and p∞.

Which lists the fundamental forces in order, from strongest to weakest? strong nuclear, weak nuclear, electromagnetic, gravitational strong nuclear, electromagnetic, weak nuclear, gravitational gravitational, weak nuclear, electromagnetic, strong nuclear electromagnetic, gravitational, strong nuclear, weak nuclear

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
