Reinforced concrete is elastic and has a compressive strength that is much higher than its tensile strength.

Determine the required splice length for the epoxy-coated longitudinal bars in the following tied column made of lightweight concrete. Assume that some of the longitudinal bars are in tension and that the connection should be designed as a Class B contact lap splice. Use ACI 318-14 Table 25.4.2.2 to calculate the development length, and assume that the ties satisfy the Code minimum.Column width, b = 22 in.Column thickness, h = 14 in.Clear cover to ties = 1.5 in.Number of longitudinal bars = 6Size of longitudinal bars = No. 10Size of ties = No. 3Concrete strength = 5,500 psiYield strength of longitudinal bars = 60,000 psiYield strength of ties = 40,000 psi

CathFoods will release a new range of candies which contain anti-oxidants. New equipment to manufacture the candy will cost  which will be depreciated by straight-line depreciation over five years. In addition, there will be  spent on promoting the new candy line. It is expected that the range of candies will bring in revenues of  per year for five years with production and support costs of $1.5 million per year. If CathFoods’ marginal tax rate is 20%, what are the incremental earnings in the second year of this project?
