A Tide Formula Component Crank on Tide Predicting Machine No. 2

A tide forumula component crank on Tide Predicting Machine No. 2, a special purpose mechanical analog computer for predicting the height and time of high and low tides. The mechanical arrangement (a slotted crank yoke) converts circular motion to a vertical motion that traces a sinusoid. The operator adjusts the position of the pin on the crank to represent a component of the tide formula at a specific coastal port before starting computations. The pin position affects the amplitude and phase of the sinusoid. The U.S. government used Tide Predicting Machine No. 2 from 1910 to 1965 to produce its tide predictions. The machine, also known as â€œOld Brass Brains,â€ uses an intricate arrangement of gears, pulleys, chains, slides, and other mechanical components to perform the computations. A person using the machine would require 2-3 days to compute a yearâ€™s tides at one location. A person performing the same calculations by hand would require hundreds of days to perform the work. The machine is 10.8 feet (3.3 m) long, 6.2 feet (1.9 m) high, and 2.0 feet (0.61 m) wide and weighs approximately 2,500 pounds (1134 kg). The operator powers the machine with a hand crank.

Mechanically Adding Trigonometric Functions

These components perform key computations for Tide Predicting Machine No. 2, a special purpose mechanical analog computer for predicting the height and time of high and low tides. The tide prediction formula implemented by the machine includes the addition of a series of cosine terms. The triangular metal pieces are part of slotted yoke cranks which convert circular motion to a vertical motion that traces a sinusoid. Each slotted yoke crank is connected by a shaft to a pulley, which causes the pulley to follow the sinusoidal motion. A chain going over and under pulleys sums each of their deflections to compute the tide.

Arizona Snowbowl Grand Canyon Express Ski Lift Opening Celebration

On December 10, 2016, the Arizona Snowbowl Ski Resort opened the new Grand Canyon Express ski lift. As part of the celebration, the resort offered free rides on the new lift to members of the public, served hot chocolate and s'mores, and lit a bonfire to keep revelers warm. Offering skiing and snowboarding on Arizona's highest mountain, the SnowBowl ski resort is a full service downhill ski area. Runs range from beginner to advanced, so there's opportunities for everyone to have fun. The resort offers rentals, lessons, and childcare. The Snowbowl usually opens in early December and remains open until mid-April. In summer months, the Arizona Snowbowl operates one of the lifts as a scenic ride. The Arizona Snowbowl is operated by permit from the Coconino National Forest. Photo taken December 10, 2016 by Deborah Lee Soltesz. Credit: U.S. Forest Service Coconino National Forest.

Fay Canyon Trail

Fay Canyon is a favorite hike for many who prefer a shorter hike with minimal elevation gain or who enjoy the grandeur of red sandstone walls towering overhead. Some people visit Fay Canyon to see the natural arch located just under a half mile up the trail. Those who don't know about it usually walk right past. Though the Fay Canyon Arch is by no means small, it looks so much like an ordinary rock overhang, it's easy to glance right at it and not realize what you've seen. If you keep watching the rock wall to the north (right) side of the trail sooner or later you'll spot it. This small, hidden canyon supports a diverse community of desert plants and provides good views of the surrounding cliffs. It dead ends at a red Supai sandstone cliff. Throughout Fay Canyon you can marvel at the breathtaking scenery that surrounds you. Photo by Deborah Lee Soltesz, January 5, 2011. Credit: Coconino National Forest, U.S. Forest Service.

Fay Canyon Trail

Fay Canyon is a favorite hike for many who prefer a shorter hike with minimal elevation gain or who enjoy the grandeur of red sandstone walls towering overhead. Some people visit Fay Canyon to see the natural arch located just under a half mile up the trail. Those who don't know about it usually walk right past. Though the Fay Canyon Arch is by no means small, it looks so much like an ordinary rock overhang, it's easy to glance right at it and not realize what you've seen. If you keep watching the rock wall to the north (right) side of the trail sooner or later you'll spot it. This small, hidden canyon supports a diverse community of desert plants and provides good views of the surrounding cliffs. It dead ends at a red Supai sandstone cliff. Throughout Fay Canyon you can marvel at the breathtaking scenery that surrounds you. Photo by Deborah Lee Soltesz, January 5, 2011. Credit: Coconino National Forest, U.S. Forest Service.

Tide Formula Component Cranks on Tide Predicting Machine No. 2

Tide formula component cranks on Tide Predicting Machine No. 2, a special purpose mechanical analog computer for predicting the height and time of high and low tides. The mechanical arrangement (a slotted crank yoke) converts circular motion to a sinusoidal motion. The operator adjusts the position of the pin on each crank to represent the tide formula at a specific port before starting computations. The pin position affects the amplitude and phase of the sinusoid. The U.S. government used Tide Predicting Machine No. 2 from 1910 to 1965 to predict tides for ports around the world. The machine, also known as â€œOld Brass Brains,â€ uses an intricate arrangement of gears, pulleys, chains, slides, and other mechanical components to perform the computations. A person using the machine would require 2-3 days to compute a yearâ€™s tides at one location. A person performing the same calculations by hand would require hundreds of days to perform the work. The machine is 10.8 feet (3.3 m) long, 6.2 feet (1.9 m) high, and 2.0 feet (0.61 m) wide and weighs approximately 2,500 pounds (1134 kg). The operator powers the machine with a hand crank.
