A sleeve coupling is used to connect two 50 mm shafts whose safe shearing stress is 70 MPa. Design the sleeve when it is made of cast iron with an ultimate shearing stress of 140 MPa. Also determine the factor of safety for which the sleeve has been designed. The length of the key is half the length of sleeve and the section of the key is 12.5 mm x 12.5 mm, find the shearing and crushing stresses induced in the key used.

Design a muff coupling to connect two shafts transmitting 40 kW at 120 r.p.m. The permissible shear and crushing stress for the shaft and key material (mild steel) are 30 MPa and 80 MPa respectively. The material of muff is cast iron with permissible shear stress of 15 MPa. Assume that the maximum torque transmitted is 25 per cent greater than the mean torque.

There are two types of ladders on the market that can be used for painting: Safe ladders which cost $6 and Risky ladders which cost $4. The probability of falling (accidently) off the Safe ladder is 0.10 and the probability of falling off the risky ladder is 0.40. If the painter does not fall then the income (I) from painting is $20, if the painter falls then income is $12. Lower income might be because the painter can’t work the...

Suppose, for simplicity, that there are two kinds of used cars in the market. Exactly 50% of the cars are good cars worth $10,000, and 50% are bad cars (lemons) worth only $5,000. Also suppose that only the car owner truly knows the type of car that it is. A.If both kinds of cars are sold, what is your expected value from buying a used car? B.Now suppose that current owners of good cars (i.e., the sellers) have a reservation...

Two cross-country running teams, called the Gazelles and the Cheetahs, participated in a (hypothetical) study in which 50% of the Gazelles and 65% of the Cheetahs used weight training to supplement a running workout.
Two cross-country running teams, called the Gazelles and the Cheetahs, participated in a (hypothetical) study in which 50% of the Gazelles and 65% of the Cheetahs used weight training to supplement a running workout. The remaining runners did not use weight training. At the end of the season, the mean improvement in race times (in seconds) for each team was as shown in the table below.Describe how the results recorded in the table might seem surprising or paradoxical.
