Ahollow spherical iron container with outer diameter 20 cm and thickness 0.2 cm is filled with iced water at 0°c. if the outer surface temperature is 5°c, determine the approximate rate of heat loss from the sphere, in kw, and the rate at which ice melts in the container. the heat of fusion of water is 333.7 kj/kg.

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.

Ifa component is made of two or more materials with different modulus of elasticity (e), it is called a composite member and we calculate the factor·n". mention the formula for calculating n". also, ifn> 1, explain what will happen to the 1. transformed.gi) ifn 1, what will happen to the material when transformed material when
