the revolving joint type v of an industrial robot has a range of 240? rotation. the mechanical errors in the joint and
in figure below a charged particle moves into a region of uniform magnetic field goes through half a circle and then
canon at an angle 30 degree tube is rotating at an axes with anguar velocities w1 and w2 2 and 5 rad/s and tube blows a ball at b with constant rate 7 m/s . what is velocity and acceleration of ball at tube end ball is at distance of 3m from tube ..
A plane can fly 299 mph in still air. If it can fly 180 miles downwind in the same amount of time it can fly 119 miles upwind, find the velocity of the wind.
The car travels up the hill with a speed of v = (0.4s) m/s, where s is in meters, measured from A. Determine the magnitude of its acceleration when it is at point s = 50 m, where p = 500 m.
a cylindrical drill with radius r1 is used to bore vertically a hole through the centre of a sphere of radius r2.a find
Friction between the piston and cylinder wall can be neglected because the process occurs so slowly. For the air, determine the initial and final pressures in kPa and the boundary work for the process in kJ.
