A flange mounted shear pin is used on a shaft as a safety device. The steel shear pin has a diameter of 2.38 mm and is to be mounted on the flange of shaft rotating at 650 rpm. The maximum power transmitted by the shaft is 4.5 KW. If the shear strength of material of pin is 30 MPa, the radial distance of its mounting is ____ Correct Answer 47.94 mm

Kw = 8.225 * N * rs * d2 * Ss * 10-8 4.5 = 8.225 * 650 * rs * (2.38)2 * 310 rs = 47.94 mm.

In the question below, are given a statement followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the following suggested courses of actions logically follow(s) for pursuing. Statement: Starting October, all new cars will have pedestrian safety features, including new design of the bonnet, to reduce impact on pedestrians during accidents. Advanced safety features are needed in all vehicles in India as vehicle safety cannot be confined to luxury vehicles only. Around 1.5 lakh people are killed in road accidents every year in the country, nearly 60% of them are pedestrians.  Courses of action: I. The government has set a target to reduce the number of road deaths by half in the next two years. The ministry of road transport and highways has been issuing new safety standards for the automobiles along with eliminating the black spots on national highways.  II. By next month, all new cars will have pedestrian safety feature, including new design of the bonnet, to reduce impact on pedestrians during accidents.  III. Ministry of road transport and Highways is planning to implement all safety features in vehicles with active support of vehicle manufacturers. Electronic stability control (ESC) and autonomous emergency braking (AEB) will be incorporated in new vehicles by 2022.
