How do you calculate the rate of plate movement?

Use the formula (island distance from hotspot ÷ island age) to calculate the rate of movement for 1. each island in the chart, then multiply by . 1 to convert from kilometers per million years to centimeters per year.

How can the rate of plate movement be determined?

Scientists first estimated the rate of plate movement based on radiometric dating of ocean crust. By determining the age of a crustal sample, and knowing its distance from the MOR at which it formed, they estimate the rate of new ocean floor production and plate movement.

What is the rate of the movement of the plate?

The majority of the research shows that the plates move at the average rate of between approximately 0.60 cm/yr to 10 cm/yr.

What information and measurements would you need to calculate the rate of plate movement?

Remember, a rate of movement (velocity) can be calculated if you know the distance traveled and the time it took to make the “trip,” according to the following formula: velocity = (distance traveled) / (travel time), or more simply, v = d / t.

How do you measure a plate?

Measure from the very outside edge of the rim, straight across the plate to the very outside edge of the rim on the other side. That measurement will be the diameter. If you measure completely around the outside edge, that measurement will be the circumference.

What is the standard plate size?

Dinner plates are most commonly 10 inches in diameter. This size is ideal since dinners usually have more than one aspect to them. A 10-inch dinner plate can hold a protein, a grain, and a vegetable without feeling too overwhelming.

What size is a plate?

What size are most dinner plates? Traditionally, a standard dinner plate has always had a diameter of 10.5 inches. In recent years, however, increasing numbers of restaurants have chosen to use larger 11 or 12 inch plates.

How many dimensions does a force plate measure?

The force plate is capable of measuring reaction forces in all three dimensions: the vertical (z axis), the horizontal (y axis), and the transverse direction (x axis).

How do force plates measure force?

Force plates are mechanical sensing systems designed to measure the ground reaction forces and moments involved in human movements. A force plate relies on the use of load cells to determine forces. The load cells may contain piezoelectric elements, strain gauges, or beam load cells [21, 22].

How is a force measured?

Force is measured in Newtons, which are units that equal 1 kg * m/sec2. You can calculate the amount of force that an object experiences with the equation force = mass * acceleration.

How do you read a force plate?

Quote from video:So 680 Newtons there that's when it returned to a normal body weight so in this case we've taken as opposed that 0.1 of a second and this time is up to 0.4 eighth of a second. So for that 0.12.

How do you calculate the jump height of a force plate?

You can do it by calculating vertical acceleration from vertical force data; a=F/m, and double integration of acceleration with time to obtain the vertical displacement. Then, subtract the vertical displacement when standing from highest vertical displacement, this value equal jump height.

How do you find velocity from force plate data?

Net force = force minus body weight. Acceleration = net force ÷ body mass (body weight ÷ the acceleration of gravity [9.81 m/s/s]) Velocity = acceleration × time. Displacement = velocity × time.

Does a force plate measure impulse?

The Force Plate, like any sensor, has a limit to how quickly it can respond to a change. If a very short impulse is applied to the force plate, it will vibrate, or ring, for a short while.

How do you measure impulse?

The impulse experienced by the object equals the change in momentum of the object. In equation form, F • t = m • Δ v. In a collision, objects experience an impulse; the impulse causes and is equal to the change in momentum.

Are force plates accurate?

Pressure plates can measure force, but only vertical force through the summation of all the sensors bearing weight. This leads them to have less accuracy, but still allows them to provide valid and usable data for some circumstances.

How does the Vernier force plate Work?

Quote from video:This is the vernier force plate. It. Allows us to measure larger forces than our dual-range force sensor. You might use this with kind of human size forces. It kind of looks like a bathroom scale.

How do you calibrate a force plate?

Set the Force Plate on a level surface and remove all force from the Force Plate. Enter 0 (zero). Second point: apply a known force (known mass) to the Plate. To obtain a good calibration, the weight should be at least 25% of the range used for the plate (200 or 850 N).

How do you use a dual range force sensor?

Quote from video:It is essentially a spring scale. And the way it operates is that if you apply maybe you have a pull to it or a push to it it's measuring the force that you're applying to the sensor.

What are vernier calipers?

A vernier caliper is usually used to measure the diameter of circular objects. The circular jaws of the vernier caliper fit perfectly on the circumference of round objects. Vernier caliper consists of two scales, the main scale which is fixed, and a moving vernier scale. The main scale has readings in millimeters.

What is MSD and VSD?

One main scale division (MSD) is the distance between two successive marks on the main scale. It is given in the figure 1 that 1 MSD is equal to 1 mm. One Vernier scale division (VSD) is the distance between two successive marks on the Vernier scale. It is given that 10 VSD = 9 MSD.

Why main scale is marked on both sides of zero?

Its name reflects the way it is used to measure the radii of curvature of spherical surfaces. It is based on the principle of screw. … On the new spherometer, the vertical scale is marked off in units of 0.5 mm.

How is screw gauge calculated?

Screw Gauge Formula



Total Reading = Pitch Scale Reading + Circular Scale Reading x LC of the gauge.

What is the formula for least count of screw gauge?

The least count of a screw gauge is L. C=p/n=1mm/100=0.

How do I calculate least count?

Least count of a Vernier scale is calculated using the following formula, Least count = Smallest reading on main scaleNumber of divisions on Vernier scale=1mm10 = This is the least count for Vernier Callipers. Hence, the least count for Vernier Callipers is 0.1mm.
