A 812 kg engine is suspended from the crane boom at point B as shown in the figure below. Using the equations of equilibrium, determine the resultant internal axial force in diagonal member CD. Your numerical answer should be given in units of N, rounded to the nearest whole number. Calculated answers within +/- 2% of the correct answer will be accepted. D D 1.5 m A C E -1 m-1 m-1 m- B

Andrew Thomas, a sandwich vendor at Hard Rock Cafe's annual Rockfest, created a table of conditional values for the various alternatives (stocking decision) and states of nature (size of crowd) States of Nature (demand) Average $12,000 $9,000 $8,100 Big Small $22,000 -$2,000 Alternatives Large Stock Average Stock Small Stock $12,000 $6,000 $9,000 $4,000 The probabilities associated with the states of nature are 0.20 for a big demand, 0.45 for an average demand, and 0.35 for a small demand a) The alternative that provides Andrew Thomas the greatest expected monetary value (EMV) is

Using the 1st law of  Thermodynamics  solve the following problem and the format of the answer is as follow a.) given:b) required:c solution : The 2M Company supplies 50 kilograms of chicken to ABEst Restaurant, which is contained in a box at 6°C, and is to be frozen at-18°C. The container box is 1.5 kg and the specific heat of the box material is 1.4 kJ/kg-°C. The freezing temperature of chicken is -2.8 °C. Determine the amount of heat that needs to be removed

A machine can be purchased at t = 0 for $20,000. The estimated life is 5 years, with an estimated salvage value of zero at that time. The average annual operating and maintenance expenses are expected to be $5,500. If MARR = 10%, what must the average annual revenues be in order to be indifferent between (a) purchasing the machine or (b) doing nothing?

Given this frequency distribution, what demand values would be associated with the following random numbers? (Do not round intermediate calculations.)  Demand Frequency 0 18 1 15 2 18 3 49 Random Numbers.     Stimulated Demand 0.2 0.5 0.5
