Chapter 4, Problem 47P

3-14. The 20-N horizontal force acts on the handle of the socket wrench. What is the moment of this force about point B. Specify the coordinate direction angles a, B, y of the moment axis. 20 N -200 mm 50 mm 10 mm У

Q3/ The 30-N force P is applied perpendicular to the portion BC of the bent bar. Determine the moment of P about point B and about point A (in two different ways). P = 30 N C 1.6 m 45° 1.6 m

Throught Scalar analysis where F is the scalar component. Determine the Vector momnent fromed by the Force F on the Point of O determine the magnitude of the moment

Determine the moment about the origin O of the force F= -21-3j+5k that acts at point A. Assume that the position vector of A is F = 4î+63 - 10k. Also, determine the equivalent force (if possible) that could be applied at F = 41+33 +5k that would induce the same effect. If it is not possible, show/explain why not.

Q-1 Caleulate the magnitude of the moment about the base point O of the 600-N force in five different ways. 600 N 0-2 Determine the moment of -875 mm- the 800-N force about point A and about point 0. 625 mm 30 F= 800 N F = 120 N 13 20 Q-3 In stendily turning the water pump, a person exerts the 120-N force on the handle as shown. Determine the moment of this force about point O. 150 mm Ans. Mo-14.74 N-m CW

The man in the figure draws the rope tied at point A.It pulls with a force of F=150 N. According to this manWrite the force F exerted by it as a Cartesian vector andDetermine the moment about point O.

P3-2. set up the determinant to find the moment of the force about point P. -3 m 22 m 2 m 1m = {21 – 4j – 3k} kN
