Engineering Mechanics: Statics . Chapter 6B: Applications of Friction in Machines. Wedges. Used to produce small position adjustments of a body or to apply large forces

Two long parallel wires 20 cm apart carry currents of 5A and 8A in the same direction. Is there any point between the two wires where the magnetic field is zero?. Yes, midway between the wires. Yes, 12 cm from the 5A wire. Yes, 7.7 cm from the 5A wire. No.

Balanced and Unbalanced Forces. When the forces acting on the car are balanced , the resultant force is zero. It stops accelerating and moves at a constant speed.

Hydrostatic Forces on Curved, Submerged Surfaces. x. Pressure is always acting perpendicular to the solid surface since there is no shear motion in static condition. P z. P. q. P x. Z. q. q. dA x =dAcos( q ). dA z =dAsin( q ). Projected Forces. x. h. dA z. Z. Integrated over

KNR 352: Quantitative Analysis in Biomechanics. Dr. Steve McCaw 227B 438-3804 www.castonline.ilstu.edu/mccaw. Topics. Basic Operations required Dealing with vectors Review from 282 (Basic Biomechanics) Kinematics Calculations of basic quantities Displacement, velocity, acceleration

Newton’s First Law - Inertia. Chapter Four. Aristotle on Motion. Greek scientist – 400 BC Two types of Motion Natural – Straight-up motion (smoke) or straight-down motion (falling) or circular (planets) Objects would seek their “natural” resting places Not thought to be caused by forces.

Biomechanics 3. Composition of Forces. Daniel Jandačka , PhD. The net force is a vector produced when two or more forces act on a single object. It is calculated by vector addition of the force vectors acting on the object. Squat Jump of Shot P utter with barbell

Up, Up and Away. January 25, 2006. Calendar. Today Some problems on vectors Introduction to some 2D issues Friday, Monday 2D Kinematics Wednesday Exam #1 – Through 2D Stuff finished on Monday Friday Going around in circles.

Resultant Forces. If two forces act together on an object, their effect may be described as the action of one force. EXAMPLE. Two forces of magnitude 5N and 6N act on a particle. They act at right angles. Find the magnitude and direction of their resultant. EXAMPLE.

EQUIVALENT FORCE-COUPLE SYSTEMS. Section’s Objectives : Students will be able to: 1) Determine the effect of moving a force. 2) Find an equivalent force-couple system for a system of forces and couples. In-Class Activities : Check homework, if any Reading quiz

Finite Control Volume Analysis. Application of Reynolds Transport Theorem. CEE 331 April 1, 2014. Moving from a System to a Control Volume. Mass Linear Momentum Moment of Momentum Energy Putting it all together!. Conservation of Mass. B = Total amount of ____ in the system

Forces on Submerged Surfaces in Static Fluids. We will use these to analyze and obtain expressions for the forces on submerged surfaces. In doing this it should also be clear the difference between: · Pressure which is a scalar quantity whose value is equal in all directions and,

Newton’s Laws of Motion. First Law. If there is no resultant force (overall force) on an object, it does not accelerate it continues to move with constant speed in one fixed direction The speed could be zero – i.e. it stays still . Second Law.

Chapter 15. Electric Forces and Electric Fields. A Bit of History. Ancient Greeks Observed electric and magnetic phenomena as early as 700 BC Found that amber, when rubbed, became electrified and attracted pieces of straw or feathers

Engineering Mechanics: Statics . Chapter 5: Distributed Forces. Introduction. ‘Concentrated’ force does not exist, since every force applied mechanically is distributed over a finite contact area.

Chapter 9 Tides. Essentials of Oceanography 7 th Edition. What causes tides?. Tides are created by the imbalance between two forces: Gravitational force of the Moon and Sun on Earth If mass increases (  ), then gravitational force increases (  )
