Chapter 2, Problem 96P

From point P to O so that the OP rope is at the point O (0,0,0) in the Cartesian coordinate system It is stretched by the force F towards the point. | OP | = 5 m, Fx = 3.5 kN, Fy = --2.5 kN and Fz = - 4.5 kN Find the P (x, y, z) coordinate. Show by drawing SCD

b. Express the force in Cartesian vector form. F = 1000 Ib 25° 130°

Find the resultant and direction of the following forces using the graphical method: F1 = 20 N, 30 degrees NE, F2 = 15 N, 50 degrees NW, 10 N, south

Q.1: Determine the magnitude and coordinate direction angles of the resultant force, and sketch this vector on the coordinate system. F3 =200 N F, =160 N 60 F =140 N 40

9. Express the force F= 1200 N in Cartesian vector form. 4 m m F = 900 N 2 m B 2m

The moment of the force F=360-lb about the point O in Cartesian vector form is. 1 ft OB 4 ft' 2 ft 4 ft. Select one: 1200/-

Given the Position vector Ř = i+j+3k (m) and the Force vector F = i - 7j + 2k (kN Determine the angle in degrees between the two vectors. Answer:

F = 525 N 0 6: Determine the magnitude and coordinate direction 120 angles of the resultant force, and sketch this vector on 45° the coordinate system. F = 450 N

2. A cleat on a boat is used to support forces from three ropes as shown. Determine the resultant force vector R, using Cartesian representation, and determine the magnitude R. Also, express R in polar vector representation. F2 = 200 N F1 = 400 N 40° F3 = 100 N 12 30°
