Answer:
D) the second at the doorknob
Explanation:
The torque exerted by a force is given by:
where
F is the magnitude of the force
d is the distance between the point of application of the force and the centre of rotation
is the angle between the direction of the force and d
In this problem, we have:
- Two forces of equal magnitude F
- Both forces are perpendicular to the door, so
- The first force is exerted at the midpoint of the door, while the 2nd force is applied at the doorknob. This means that d is the larger for the 2nd force
--> therefore, the 2nd force exerts a greater torque
Answer:
0.44807175m
Explanation:
k = Spring constant = (Assumed, as it is not given)
g = Acceleration due to gravity = 9.81 m/s²
Total mass is
The total weight will balance the spring force
The springs are compressed by 0.44807175m
