please do question #1 in step including the conversion. Why we need to convert the force in lb instead of N? Do it simple and do it step by step. Thanks

Practice Pneumatics/Hydraulics Worksheet #1a (1) A force of 5 x 10 Newtons is applied on a circular piston face of a Double Acing Cylinder with a pressurized system of 250 psi. Calculate the diameter of the p of an inch. Show all necessary work. iston face to the nearest tenth had 0. 224 D-219) 2 1,14629 in2 The diameter of a circular piston face of a Double Acting Cylinder is 1.625 inches. The force exerted on the piston face is 175 pounds. Calculate the pressure to the nearest psi. (2) 1.625 in 2 A-tr = 10.80 Inspe 3.14 08025 in

Explanation / Answer

Ans)

Force = Pressure X area

1 psi = 6894.75 Pa

250 psi = 1723689.32 Pa

area = pi*r^2

Thus

5000 = 1723689.32*pi*r^2

r^2 = 0.000923

r= 0.304 m = 11.968 inch = 12 inches(rounded off to nearest 10th)
