Two men are pulling a tree in one direction while a third is chopping it down. The ropes make an angle of 30°. The first man pulls with a force of 430 N and the second man pulls with a force of 350 N. Use the parallelogram method (tail-to-tail method) to determine the resultant of their pulling forces.​

What is the rate of 12 liters of water moving through a water hose in 4.0 minutes?

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
