Explain Hard or Fixed Automation
Mechanical controls consist of numbers of mechanism that create the required relative motion to complete an activity. These mechanisms include: cams, levers, ways and slides, push rods, screw system. Mechanical control is difficult to fabricate and reprogram and is subject to wear. Hydraulic control is also used for fixed automation, because reprogramming is not feasible.

Determine the frictional resistance: (i) A train having weight 400 kN is running up an inclined path of 1 in 100 at a steady speed of 54 km/hour. If the frictional resistance
a concrete column of 350mm diameter is reinforced with 4 bars of 25mm diameter . find the stress when the concrete is subjected to a stress of 4.5 MPa . also find the safe load in
FRICTION WELDING In this, friction is employed to generate heat b/w two sliding or rotating metal surfaces. This process is usually carried out by placing the pieces to be welded
Determine Maximum fibre stress: A beam of rectangular section of 80 mm to 120 mm carries a uniformly distributed load of 40 kN/m over a span of 2 m an axial compressive force
Determine tension in the rope: An elevator cage of mineshaft, weighing 8KN when, is lifted or lowered by means of wire rope. Once man weighing 600N entered it and lowered wit
