To increase the velocity ratio of a single purchase crab mechanism, you can change the ratio of the radii of the drum that the rope wraps around and the radii of the axle around which the crab rotates. By increasing the radius of the drum relative to the axle, you can increase the velocity ratio. This can be achieved by either increasing the diameter of the drum or decreasing the diameter of the axle.

What are the minimum changes in set up to increase velocity ratio pf single purchase crab?
To increase the velocity ratio of a single purchase crab, you can change the diameter of the drive wheel or adjust the number of strands supporting the load. Increasing the diameter of the drive wheel will increase the velocity ratio, while adding more strands supporting the load will also enhance the mechanical advantage and thus the velocity ratio of the system.
Which term describes an increase or decrease in velocity or a change in direction?
Acceleration is the term that describes an increase or decrease in velocity or a change in direction of an object.
What refers to the rate of change in velocity?
Acceleration refers to the rate of change in velocity. It can be in the form of an increase or decrease in speed, or a change in direction.
What is a change that indicates the acceleration of an object?
An increase in speed or velocity.
What will always change when an object accelerates?
The object's velocity will change when it accelerates. Acceleration is the rate of change of velocity, so as an object accelerates, its velocity will continuously increase or decrease depending on the direction of acceleration.

When acceleration increase does velocity increase?
No. Acceleration IS a change of velocity - any change. When velocity increases, there IS acceleration. The acceleration itself may be increasing, decreasing, or remain constant.

What do you have to change for an object to have more kinetic energy?
Increase its velocity

What change would most likely increase the velocity of a river?
Increasing the gradient or slope of the river bed is most likely to increase the velocity of a river. This change allows water to flow more rapidly downhill, resulting in higher velocity.
What must applied in order to change an object's velocity?
force
How is the initial velocity zero but the acceleration is not?
Going back to definitions, Velocity is change of distance with time; and acceleration is change in velocity with time. Initially, the velocity is zero, as is the acceleration, BUT the Force of Gravity attracts the falling mass, and causes velocity to appear. But the continued application of the Force of Gravity causes the velocity to increase. And as we know, increase in velocity is acceleration. [space for QED]
Rate of change of velocity of a moving object?
The rate of change of velocity of a moving object is known as acceleration. Acceleration can be calculated by dividing the change in velocity by the time taken for the change to occur. Positive acceleration represents an increase in velocity, while negative acceleration (or deceleration) represents a decrease in velocity.
How do you find the minimum deceleration?
To find the minimum deceleration, you would need to calculate the change in velocity and time over which the deceleration occurs. Then, you can use the formula a = Δv / t, where a is the acceleration, Δv is the change in velocity, and t is the time. The minimum deceleration would be the smallest value calculated using this formula.
