Question
30 hp are supplied at 75 cm gear by means of a pinion, as shown in figure 1. In the pulley of 60 cm 20 hp is taken out and, in the 20cm crank 10 hp are taken out. The mass of the pulley is 450 kg, in order to provide some flywheel effect and rotates at 300 rev/min. The arrangement of elements and stresses in the belt are shown in Figure 1. The tangential force is Tt = 1900 kN and the radial force is Tr.= 690 N of stresses in the band is 4:1. Loads are applied with moderate shock with kf = kfs = 1.97 and kfm = kfsm = 1.54. For the 30 mm diameter shaft in figure 1, determine: a) the shear and bending moment diagrams in the vertical, horizontal and total planes; b) what is the bending moment at the bearing location that is between the gear and pulley, in kN m? c) What is the maximum bending moment on the shaft, in kN m? d) Which Are the maximum shear and normal stresses and where do they occur?

Question
Thirty horsepower is supplied to the 30in. sprocket by means of a chain drive as shown in Figure below. Twenty horsepower is taken off at the 24in. pulley which weighs 1000lb and 10hp is taken off at the 8in. crank. The force in the chain on the tight side is represented by T c ​ The tension in the slack side is so small that it can be neglected. The ratio of the tensions in the belt is 4:1. The shaft is rotating at 300rpm. The loads are applied with moderate shock, C m ​ =2 and C t ​ =1.5 determine the size of shaft necessary if S c ​ (allowable) 8000psi. It is assumed that the sprocket and pulley are keyed to the shaft.

Question
Two streams of H2O are mixed to form feed to boiler (stream A is 120 kg/ min at 30 °C and stream B is 175 kg/ min at °65 C). The existing streams emerges from the boiler through 6 cm I.D pipe. Calculate the required heat input to the boiler in KJ/min. If the system leaving is saturated steam at pressure 17 bar neglect kinetic energy of inlet stream. Given that H^A = 125.7 KJ/Kg, H^B = 217 KJ/Kg, outlet stream has H^ = 2793 KJ/Kg, V^g = 0.1166 m3/Kg?
