Q3. A rectangular cross sectioned cantilever beam is 300 mm long and has a half bridge gauge at a distance 200.0 from the free end, whose width is twice the height. If the load applied at the free end is 15 kg, the V, is measured to be 150 micro volts. The gauge factor is given as 2.14 and the applied voltage V, is given a 5V and hence the equation for half bridge is given as E a) Determine...
A cantilever beam AB with a circular cross section and length L = 750 mm supports a load P = 800 N acting at the free end (see figure). The beam is made of steel with an allowable bending stress of l20 MPa. Determine the required diameter d_min (figure part a) of the beam, considering the effect of the beam's own weight. Repeat part (a) if the beam is hollow with wall thickness t = d/8 (figure part b); compare...

QI A cantilever beam carries a horizontal point load of 100 kN at its end, as shown in Figure Q1 (a). In this case, the self weight of the beam must be included. The beam is made from a square box section with a width of b and a depth of b (refer to Figure Q1 (b)). The density of the beam is 20 kN/m and the maximum allowable longitudinal stress of the beam is 200 N/mm². Figure QI (a)...
Q2 A simply supported beam of length L = 10 m carries both a uniformly distributed load wy of 10 kN/m and a non-uniformly distributed load with a maximum value of w2 =10 kN/m at its roller support, as shown in Figure Q2 (a).

Self-weight of the beam is neglected. 300...
A simple beam AB of span length L 6.7 m (Fig. 5-14a) supports a uniform load of intensity q 22 kN/m and a concentrated load P 50 kN. The uni- form load includes an allowance for the weight of the beam. The concen trated load acts at a point 2.5 m from the left-hand end of the beam.
