1.Find the reactions at A, B, C, and D. Neglect friction.
2.A roller of weight W=1000N rest on a smooth incline plane. It is kept from rolling down the plane by a string AC. Find the tension in the string and reaction at the point of contact D.
3.A uniform wheel of 800 mm diameter, weighing 6kN rests against a rigid rectangular block of 150 mm height as shown in figure. Find the least pull through the centre of the wheel required just to turn the wheel over the corner A of the block. Also find the reaction on the block .Take all the surface to be smooth.
4.Forces act on the plate ABCD as shown in figure. The distance AB is 4 m. Given that the plate is in equilibrium find. (i) force F (ii) angle α and the (iii) the distance AD
6.Determine reactions at A, B and C for the frame shown in figure.
7.Two Cylinders each of diameter 100 mm and each weighing 200N are placed as shown in figure. Assuming that all the contact surfaces are smooth find the reactions at A,B and C.
