What is the relationship between the angle of incline and mechanical advantage?
hj
What is a compound angle?
In mechanical design, a coumpound angle is the resultant of two individual angles that are perpendicular to each other.
Why is a spanner bent at an angle?
The spanner is bent at an angle so that it can easily applied or hold the grip of any 6 sides of nut to achieve the maximum mechanical advantage by moving the handle to and fro in the shortest possible space.
What is the mechanical advantage of a 5 meter ramp lifting an object to a height of 0.75 meters?
MA = 5 / 0.75 = 6.67 Essentially, its the reciprocal of the sin of the ramp angle
What are the fomulas for incline plane?
( Assuming mass of object on incline plane is in kilograms (kg) ) . Force pulling down incline on object (kilogram force) = object mass * sin (incline angle) . Force of object acting on and normal to incline (kilogram force) = object mass * cos (incline angle) . Mechanical Advantage = 1 / ( sin ( incline angle ) )
What is difference between electrical angle and mechanical angle?
Electrical angle is half of mechanical angle in unipolar electrical machines. In multipolar electrical machines, the relationship between the mechanical angle and electrical angle is Electrical angle = (P/2) x Mechanical angle where: P = Number of poles.
Does Increasing the angle a ramp makes with the horizontal decreases the mechanical advantage?
No, increasing the angle of a ramp actually increases the mechanical advantage. Mechanical advantage is calculated as the length of the slope of the ramp divided by the vertical height it spans. As the angle of the ramp increases, the slope length increases, resulting in a higher mechanical advantage.
How do you the Mechanical advantage of a wedge?
Just change the angle of the wedge. The thinner the wedge, the greater the mechanical advantage.
What is the relationship between the angle of incline and mechanical advantage?
hj
What is a compound angle?
In mechanical design, a coumpound angle is the resultant of two individual angles that are perpendicular to each other.
Why does the mechanical advantage of an inclined plane decrease as you increase the angle of inclination?
At the two extremes of the angle of inclination you have no mechanical advantage. At an angle of 0 degrees, the plane is parallel to the effort force so it cannot raise the load. At the angle of 90 degrees, the plane is perpendicular to the effort force so all effort is directed into the plane. Between those two extremes, you have a machine. Divide the length (L) of the inclined plane by its height (H) to find the mechanical advantage. Notice that in the case where the angle of inclination is 0 degrees, H = 0. Division by zero is not allowed in math. (The mechanical advantage is undefined.) In the case where the inclination is 90 degrees, L = 0, 0/L = 0 (No mechanical advantage).
How do you calculate the ideal mechanical advantage of an inclined plane?
Its the reciprocal of the sine of the ramp angle. > 1 / ( sin ( ramp angle ) )
What are two ways of increasing the mechanical advantage of an inclined plane?
One way to increase the mechanical advantage of an inclined plane is to increase the length of the plane, which reduces the slope angle. Another way is to decrease the height of the plane relative to its length, which also reduces the slope angle.
Is it true that increasing the angle a ramp makes with the horizontal decreases mechanical advantage?
No, increasing the angle of a ramp actually increases the mechanical advantage. This is because a steeper ramp allows for a smaller input force to lift an object against gravity. However, it may also increase the distance over which the force must be applied.
How do you increase the mechanical advantage of a wedge?
The spokes of a wheel are comparable to levers. Longer spokes give more mechanical advantage. Even in a wheel that is solid, and has no spokes, the greater the diameter, the greater the mechanical advantage.
Why is a spanner bent at an angle?
The spanner is bent at an angle so that it can easily applied or hold the grip of any 6 sides of nut to achieve the maximum mechanical advantage by moving the handle to and fro in the shortest possible space.
Which would increase mechanical advantage of a ramp?
Increasing the length of the ramp or decreasing the angle of incline would increase the mechanical advantage of a ramp. This would make it easier to move objects up the ramp by requiring less force.
