    Why Is the Fringe at the Narrow End of a Wedge Always Dark?

    For a solid wedge of material of length L and maximum width D (ie, a triangle) how would one obtain an equation for /\x, the distance between dark fringes? For wedge fringes, how come the fringe at the narrow end is always dark?

    Finding Velocity and Height of Wedge After Block Release

    A small block of mass .5kg is released form rest at the top of a curved-shaped frictionless wedge of mass 3 kg , which sits on a frictionless horizontal surfces. When the block leaves the wedge, its velocity is 4 m/s to the right. Find the velocity of the wedge after the block reaches the...

    What is the height of the wedge?

    A small block of mass .5kg is released form rest at the top of a curved-shaped frictionless wedge of mass 3 kg , which sits on a frictionless horizontal surfces. When the block leaves the wedge, its velocity is 4 m/s to the right. Find the velocity of the wedge after the block reaches the...

    Evaluating Volume of Curved Wedge Cut from Cylinder

    Trying to do this question: 'Evaluate the volume of the following solids... A curved wedge that is cut from a cylinder of radius 3m by two planes. One plane is perpendicular to the axis of the cylinder. The other plane crosses the first plane at 45 degree angle at the centre of the cylinder.'...

    Calculate Radius of Wire in Air Wedge Formed by Glass Plates

    An air wedge is formed between two glass plates separated at one edge by a ver fine wire. When the wedge is illumindated from above by 688 nm light, 29 dark fringes are observed. Calculate the radius of the wire. Show answer in micro meters I have tried many different things with this...

    Block and Wedge (all frictionless)

    I searched for this problem and could not find satisfactory information or information that applied to my specific concerns. The wedge of mass M is resting on a horizontal surface. A block of mass m is placed on the wedge and the whole system is released from rest. There is no friction...

    Physical Optics : Air Wedge - Interference

    Hi there, I was doing some past year paper of my coming exam...and I got the answers for the question too, but one part I'm totally blur and can't understand that well... well here goes all the questions and solution: http://server3.uploadit.org/files/chickens-phyQ.jpg...

    Good old wedge and block sliding problem

    The problem is as follows. We know the angle of the wedge to the horizontal. Let's say its a given. We don't know the mass of the wedge or the mass of the block. The planes are frictionless. The mass rests on a "frictionless table". There is a force pushing the entire system. The...

    Calculating Normal Force on Block on Wedge

    A block of mass m is placed on a wedge. The wedge is pushed along a horizontal surface with accelertation a, so that the block stays in place on the wedge, even though there is no friction between the block and the wedge. The normal force acting on the block during the acceleration is equal to...

    Frictionless Equilibrium of Block and Wedge System

    Hello, I am new member here. I would like to know how should I handle this question: A block of mass 2.5kg rests on the rough surface of a wedge, which in turn rests on a rough horizontal floor. What is the frictional force exerted by the floor on the wedge if the whole system is at rest...

    Deriving Velocity of Wedge Before Block Hits Ground

    simple question: a movable block on a movable wedge on some frictionless ground. we know all masses, angles, and there is no friction. the block starts on the wedge at some height h, and slides down the wedge. the block moves forwards, and the wedge moves backwards. what is the velocity of the...

    Problem on block sliding on a wedge

    Consider a block of mass 'm' kept on the hypotenuse of a right triangular wedge of mass 'M'. Calculate the accelaration of the wedge and the block. Hence find the force that should be applied to 'M' so that 'm' does not move?

    Transforming a Wedge into an Angular Sector

    Okay, I'm having trouble understanding the following: Given a region of a circular wedge with endpoints a and b, the mapping z_{1}=\frac{z-a}{z-b} transforms this wedge into an angular sector. Then, by an appropriate power \alpha, the map w = z_{1}^\alpha maps the angular sector onto a half...

    Rotating Wedge & Rise of Mass: Speed Calculation

    the sloping side is frictionless, it is spun at constant speed by rotating the wedge. show that when a mass rises up the wedge a distance L, the speed of the mass is v=sqr(gLsin0) I got Fx=m(v^2/r) = mgsin0 v^2=g*sin0*r can I say r=L ? I got stuck, could you give me some hints thank you

    Solving a Geometry Problem: Area of a Circle with a Wedge

    i made a pretty picture but i can't get it to upload :frown: oh well...i'll try to explain it a circle of radius 3cm is inside a circle of radius 8cm (in the middle). On top of these two circles is a wedge (i think...it's like a triangle except curved at the end to fit the edge of the...

    Friction-less wedge physics problem

    A 2.0-kg body rests on a frictionless wedge that has an inclination of 65.0° and an acceleration a to the right such that the mass remains stationary relative to the wedge. Find a This is one of the question i had to do for HW. Not really asking for an answer but it would be great if you...
