Chapter 8, Problem 20ICA
A eutectic alloy of two metals contains the specific percentage of each metal that gives the lowest possible melting temperature for any combination of those two metals. Eutectic alloys are often used for soldering electronic components to minimize the possibility of thermal damage. In the past, the most common eutectic alloy used in this application has been 63% Sn, 37% Pb, with a melting temperature of about 361 degrees Fahrenheit [°F], To reduce lead pollution in the environment, many other alloys have been tried, including those in the table below. Complete the following table:
| Eutectic Temperature | |||||
| Compound | [°F] | [°C] | [K] | [°R] | |
| (a) | 91% Sn, 9% Zn | 472 | |||
| (b) | 96.5% Sn, 3.5% Ag | 890 | |||

A piston with a weight of 29.4 N is supported by a spring
and dashpot. A dashpot of damping coefficient c = 275
N.s/m acts in parallel with the spring of stiffness k = 2400
N/m. A fluctuating pressure p = 960 sin 30t N/m² acts on
the piston, whose top surface area is 0.05 m². Determine
the steady-state displacement as a function of time and the
maximum force transmitted to the base.

9. Design a spur gear drive required to transmit 45 kW at a pinion speed of 800 r.p.m. The velocity ratio
is 3.5 : 1. The teeth are 20° full-depth involute with 18 teeth on the pinion. Both the pinion and gear
are made of steel with a maximum safe static stress of 180 MPa. Assume a safe stress of 40 MPa for
the material of the shaft and key.
10. Design a pair of spur gears with stub teeth to transmit 55 kW from a 175 mm pinion running at 2500
r.p.m. to a gear running at 1500 r.p.m. Both the gears are made of steel having B.H.N. 260. Approximate
the pitch by means of Lewis equation and then adjust the dimensions to keep within the limits set by
the dynamic load and wear equation.
7. A motor shaft rotating at 1440 r.p.m. has to transmit 15 kW to a low speed shaft rotating at 500 r.p.m.
The teeth are 20° involute with 25 teeth on the pinion. Both the pinion and gear are made of cast iron
with a maximum safe stress of 56 MPa. A safe stress of 35 MPa may be taken for the shaft on which
the gear is mounted. Design and sketch the spur gear drive to suit the above conditions. The starting
torque may be assumed as 1,25 times the running torque.
