A rigid triangular plate is suspended from a horizontal plane by three vertical wires attached to its corners. The wires are each 1 mm diameter, 1440 mm long with a modulus of elasticity of 196 000 N/mm². The ratio of the lengths of the sides of the plate is 3:4:5. Calculate the deflection at the point of application of a load of 100 N placed at a point equidistant from the three sides of the plate. Ans. 0.33 mm.

The acrylic plastic rod is 200 mm long and 15 mm in diameter. If an axial load of 400 N is applied to it, determine the change in its length and the change in its diameter. E = 3.20 GPa, v = 0.4. %3D 400 N 400 N 200 mm

Solve it correctly please. I will rate accordingly.

A pump is driven from an engine crank-shaft by the mechanism as shown in Figure . The pump piston shown at F is 250 mm in diameter and the crank speed is 100 r.p.m. The dimensions of various links are as follows: OA = 150 mm ; AB mm; DE = 500 mm. Determine for the position shown: 1. The velocity of the cross-head E, 2. The rubbing velocity of the pins A and B which are 50 mm diameter. 3.The acceleration of the cross-head E. 45 A 300 600 mm ; BC = 350 mm ; CD = 150 %3D 450 100 1111 All dimensions in mm.

PLease solve the question step by step.....
