5.7. For the configuration shown in Fig. P5.7, determine the deflection at the point of load appli cation using a one-element model. If a mesh of several triangular elements is used, commen on the stress values in the elements close to the tip. 30 mm 100 N 20 mm t = 10 mm E=70,000 MPa v = 0.3 50 N Figure P5.7
