Does the number of tiny holes in the parachute affect its descension rate Introduction This experiment will determine if the number of tiny holes in the parachute effect will its descension rate.This science of this project includes newtons second law, drag force, gravity, velocity and terminal velocity . This experiments main focus is air resistance. Project rationale/ purpose In this experiment I will test if having small holes in a parachute help the parachute from falling as fast. This…

The T-41 (i.e., the military version of the Cessna 172) had a "simple mechanical" flight control system using direct mechanical linkages. Direct feedback of forces acting on the control surfaces to the control stick (or yoke) provided a natural feel. The feedback was by the "seat of the pants". The trim system was a mechanical linkage connected directly to a trim control wheel in the cockpit. There is no warning in the T-41 if the trim was set incorrectly. It is the pilot’s responsibility…

Did you know parachutes come in all kinds of different shapes? The shapes vary from circles to triangles. However which one is the fastest? There are many factors that effect the speed of parachutes. Kinetic and potential, for example, influence the parachutes speed and movement. When a skydiver jumps out of an airplane gravity pulls him towards the ground and he doesn’t have enough air resistance to safety land on the ground. That’s where the parachute comes in! When the skydiver pulls the…

Chapter 1 Introduction 1.1 What is aerofoil? Aerofoil is a large stucture which is attached to the airplane. It has curved surfaces designed to give required ratio of lift and drag. It helps to create different aeodynamic forces. The force perpendicular to the motion of aeofoil is lift force. The force parallel to the motion of aerofoil is drag force. 1.2 How it works? Aerofoil consists of following components: • Suction surface • Pressure surface • Leading edge • Tailing edge •…

required is then 45 deg. 2.3.2 Increased extension of the wing in the flight direction One of the major advantage of yawed/oblique wing over swept wing depensd on an increased extension of wing in the flight direction. We know that spreading the lift over a greater length weakens sonic boom intensity and drag. For a given structured slenderness the single yawed wing have nearly double the projected length of the equivalent swept…

The egg drop project we did involved many physics principles. One of them was air resistance, which happened because the egg dropped and it accelerated, while the velocity increased. Then the resistance of the air to the egg box motion also increased, which means the upward force of air resistance balances the downward force of gravity, so the egg box dropped at a constant speed. We attached balloons to the box we made in order for the box to pass through the air while softly landing. We believe…

We loved to ski, my friends and I. Every Thursday was a chance to escape into the ski hill and leave all of our problems at the door of the ski lodge. Ski club was an essential part of our lives in the winter. There was no one telling us we couldn’t eat a cookie and fries for dinner. No one telling us we can’t scream and yelp with excitement like we did on the ski hill. My friends and I were known to be the last ones on the bus, and this week would be no exception. We had just finished dinner,…

As I floated to the top of the hill on the ski lift, my stomach dropped and I grew hot despite the freezing temperatures outside. I was attempting to prepare myself for the sizable slope that I thought to be my impending doom. When I departed from the lift I turned my skis to position myself at the brink of slope. Then I tipped my skis over the edge of the hill with much initial regret. Throughout my years of skiing I had sprained joints, bruised limbs, and nearly broken bones. Despite my…

CLICK TO SHARE Man on ski slope with snow bikeIt’s a blue bird day—sun shining, no clouds in sight—and the snow beneath your blades is like satin. You got first chair and are ready to feel the wind up against your jacket. But there’s no need to strap in or grab your poles. Instead, you grab the handle bars and push off, cruising on the three “skis” of Snogo, a new downhill snow bike due to hit the market in early 2016. “I wouldn’t be on the mountain if it wasn’t for ski bikes,” says Obed…

I’m always the first one to go onto the slopes. You can’t wait for the lift to take you up, you stand in line eager to take you up the hill. You listen to your snow boot clamp against the ground as you stomp your way up to the front only to find the gondola is under repair and you must take a bus to the next one 3 miles away…
