Answer:

The work efficiency formula is efficiency = output / input, and you can multiply the result by 100 to get work efficiency as a percentage. This is used across different methods of measuring energy and work, whether it's energy production or machine efficiency.

Three forces act on an object. Two of the forces have the magnitudes 56 N and 27 N, and make angles 53° and 156°, respectively,
Ludmilka [50]

Answer:

Explanation:

Given

Two forces F_1 and F_2 at an angle of \theta _1  \theta _2

F_1=56\ N

F_2=27\ N

\theta _1=53^{\circ}

\theta _2=156^{\circ}

As resultant force is zero therefore horizontal component as well as vertical component of force is zero

\sum F_x=F_1\cos \theta _1+F_2\cos \theta _2+F_3\cos \theta _3

\sum F_x=56\cos 53+27\cos 156+F_3\cos \theta

F_3\cos \theta_3=-9.035\ N----1

\sum F_y=F_1\sin \theta _1+F_2\sin \theta _2+F_3\sin \theta _3

F_3\sin \theta _3=55.704\ N----2

squaring and adding 1 and 2

F_3^2(\cos ^2\theta _3+\sin^2\theta _3)=86.583+3102.93

F_3=56.47\ N

Divide 1 and 2 to get \theta _3

\frac{\sin \theta_3 }{\cos \theta_3 }=\frac{-55.704}{9.305}

\tan \theta_3=-6.16

\theta _3=180-80.78

\theta _3=99.22^{\circ}

Answer: a force is simply a push or pull.

The SI unit for force is Newton(N) or kgm/s2

When the net force on an object is not zero the forces are said to be unbalanced since they do not cancel out each other .

When two forces act in opposite directions we substract the forces in order to get the resultant force acting on the object.
