Chapter 4, Problem 24FP

The force-couple system consists of the force R=250i+360j400kN and the couple-vector CR=1200i+750j+560kNm. Determine the equivalent wrench and find the coordinates of the point where the axis of the wrench crosses the xy-plane.

1. Aforce F is applied to the wrench. Determine the moment of this force about point 0. Solve the problem using both a scalar analysis and a vector analysis.

Handle forces F¡ and F2 are applied to the electric drill. Replace this force system by an equivalent resultant force and couple moment acting at point 0. Express the results in Cartesian vector form. Set F, = { 3j - 6k } N and F2 = { 9i - 4.5j - 15k } N 0.15 m- 0.25 m 0.3 m

Determine the moment of force F about the door hinge at B. Express the result as a Cartesian vector.

Replace the two forces acting on the pole by a wrench. Write the force R and moment M associated with the wrench as vectors and specify the coordinates of the point P in the y-z plane through which the line of action of the wrench passes. Assume F₁ = 46 N, F₂ = 107 N, a = 1.6 m, b = 6.3 m. F₁ Answers: R=( i M = (i I Force and moment associated with wrench Coordinates of point P. (y,z) = (i F₂ T b i+ i ¡+ i i j+ i j+ ) m i k) N k) N-m

Solve it correctly please.

Handle forces F1 and F2 are applied to the electric drill. Replace this force system by an equivalent resultant force and couple moment acting at point O. Express the results in Cartesian vector from. Determine the resultant force and the moment of the resultant forse about the point O. Express your answer in terms of the unit vectors i, j and k.
