Chapter 4, Problem 37P

Determine the moment of the force F about point A in terms of F and d. Use (a) the scalar method; and (b) the vector method.

The wrench is used to tighten a nut on the wheel. Determine the moment of the 120-lb force about the origin O. Express your answer in vector form.

Calculate the resultant moment produced by two forces about point O. Express the result as a Cartesian vector.

The force F in the system shown has a magnitude of 500 N and angles directional a = 65°, B = 130° and y = 45°. Determine the moment produced by the force F around point O, if L1 = 0.4m, L2 = 0.3m and L3 = 0.5m. Express the result as a Cartesian Vector. Li L3 Lz F

If F, = {110i - 120j + 95k} N and F2 = { -160i + 240j + 95k} N, determine the resultant moment produced by these forces about point O. Express the result as a Cartesian vector. 4 m F, 5 m. 3.5 m

The man in the figure pulls the rope tied at point A with a force of F=150 N. Accordingly, write the force F exerted by the man as a cartesian vector and determine its moment with respect to point O.

Determine the moment of force F about an axis through A and C. Express the result as a Cartesian vector

SOLVE ASAPThe line of action of force F₁ = 388 N is passing through point A(+2,+3,+1) towards B(+5,+5, +4), while that of force F₂ = 488 N is through point C(+3,+1,−1) towards D(-2, -3, -4). Use a right-handed coordinate system.a. Determine the moment of force F₁ about the origin.b. Determine the moment of force F2 about the origin. c. Determine the magnitude of the resultant moment of forces Fi and F₂ about segment OE. Point O is the origin and point E is at (+5,+5,-3).

Express the 5-kN force F as a Cartesian vector in terms of the unit vectors i, j, and k.  Determine the projection of F onto the x-axis and onto line OA.  (Hint: express line OA as an arbitrary length vector and then apply the “DOT” product stuff for projections.)
