Please answer correctly
The figure below shows a claw hammer being used to pull a nail out of a horizontal board where theta = 32.2 degree. The mass of the hammer is 1.00 kg. A force of 175 N is exerted horizontally as shown, and the nail does not yet move relative to the board. Assume the force the hammer exerts on the nail is parallel to the nail. Find the force exerted by the hammer claws on the nail, magnitude Note that the answer has units of kN. kN direction Make certain you have read the comment in the problem carefully. degree above the horizontal Find the force exerted by the surface on the point of contact with the hammer head.( i^+ j^)NExplanation / Answer
sum torques about point of contact
-175*.3 + F*.05*cos(32.2) = 0
F=1240.85 N = 1.24 kN
angle = 90-32.2 = 57.8 degrees
sum forces in the x:
x - 1240.85*sin(32.2)+175 = 0
x = 1240.85*sin(32.2)-175=486.22
sum forces in the y
y - 1240.85*cos(32.2) =0
y =1240.85*cos(32.2) = 1050
so 486.22 i + 1050 j
