Replace the two parallel forces by single force:
Replace the two parallel forces acting on the control lever by a single equivalent force R.
Sol.: Since single equivalent force is resultant.
Let ΣH and ΣV be the horizontal and vertical component of the resultant. Resolving all the forces in horizontal direction
ΣH = 50 - 80 = -30N ...(i)
As there is no vertical force that is the resultant is horizontal. Now for finding out point of application of resultant, Let resultant is at distance of 'd' from the point 'O'. Apply varignon's theorem, and by taking moment about point 'O'
R.d = 50 × 80 - 80 × 50 = 0
But ΣR = ΣH = -30N, so d = 0
d = 0, means point of application of the resultant is 'O'
Therefore an equivalent force 30N acts in negative x-axis at point 'O' which replaces the given force system.

Varignon theorem: State Varignon's theorem. How it helps in determining of the moments? In which type of condition is it used? Sol.: Varignon's theorem also called Law
How can I achieve a back and forth movement of carriage system. How can I reverse the motor to go back and forth.
example on operation sheet?
can you help me to do my project on machine design,it is specific project with calculation and some draw.
Power metallurgy is much faster production whereas holding closer sizes.
