Find the force exerted by the surface on the point of contact with the hammer head. assume that the force the hammer exerts on the nail is parallel to the nail.

716.3N

Step-by-step explanation:

Moment produced by force F = 150 N:

Mf = 150 * 30 = 4500 Ncm

The same moment is imparted at the nail.

Fn * 5 / sin (60) = 4500 Ncm

Fn = 779.423 N

Force exerted by surface on hammer pivot is:

Fx = 779.423 sin (30) - 150 = 239.7115 N

Fy = 779.423 cos (30) = 675 N

Fres = sqrt ( (Fx)^2 + (Fy)^2)

Fres = sqrt ( 675 ^2 + 239.7115^2)

Fres = 716.3 N

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
