Free webinar on Robotics (Block Chain) Learn to create a Robotic Device Using Arduino
30th Jan @ 5:00PM for Grade 1 to 10
A wedge of mass M resting on a horizontal frictionless surface is acted upon by a force f in the horizontal direction as shown in the figure find the net horizontal force acting on the shaded portion of the wedge. A wedge of mass M resting on a horizontal frictionless surface is acted upon by a force f in the horizontal direction as shown in the figure find the net horizontal force acting on the shaded portion of the wedge.
find the mass of shaded portion (1/2(2h/3)2-1/2(h/3)2)*2M/h2=M(4/9-1/9)=M/3Net acceleration a=F/MForce on horizontal portion=Ma/3=F/3
