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

Replace the loading acting on the frame by an equivalent resultant force and couple moment acting at point A. 80 lb 60 lb 3 ft 3 ft- 3 ft 3 ft B A 2 ft + 4 ft 75 lb 40 lb

The 30N force P is applied perpendicular to the portion BC on the bent bar . Determine The moment of P about point B and about point A.

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.

Determine the resultant of the four forces acting the circular plate and the angle ϴ, which the resultant makes with the indicated x-axis. Show the FBD and use the parallelogram law to solve the problem.

The figure below shows a man holding a box of mass 15 kg. Determine the moment produced by the weight of the box about point E. Given that d1=0.9 m, d2-D0.4 m and d3-1.5 m. di m - di m d2 m E d3 m

Determien the resultant couple moment acting on the pipe assembly.

The design specifications for the attachment at A for this beam depend on the magnitude and location of the applied loads. Represent the resultant of the three forces and couple by a single force R at A and a couple moment. Take: M 25 kN .m ;a = 30 ; x = 1.6.m 4 kN 2 m -1.5 m- -0.8 m 2 kN 3 kN

The pipe assembly is subjected to three forces of F1 = {3.00, 4.00, -2.00} kip, F2 = {0, 0,-4.00} kip, and F3 = {-3.00, 0, 0} kip. Determine the sum of the moment of the forces 1) about x-axis (the unit vector of x is i) and 2) about line AC. Express the result as a Cartesian vector.
