Q4. A compound bar as shown in Figure Q4 carries the axial nodal forces of 10 kN at node 2 and 30 kN at node 3. Node 1 is a rigid support and node 2 is a rigid joint. The cross-sectional area (A) of members at the nodes and the length (L) and modulus of elasticity (E) of the members are shown in the figure. Analyze the compound bar using Finite Element Method by employing two-noded line element for each member, (a) calculate the displacement at node 2 and node 3, and (b) determine the axial stress in the members. $A_1 = 1255 \, mm^2$ $L = 1000 \, mm$ $E = 200 \, kN/mm^2$ $A_2 = 784 \, mm^2$ $L = 800 \, mm$ $E = 28 \, kN/mm^2$ $A_3 = 784 \, mm^2$ Figure Q4

A large national bank charges local companies for using their services. A bank official reported the results of a regression analysis designed to predict the bank's charges (Y) —measured in dollars per month—for services rendered to local companies. One independent variable used to predict service charges to a company is the company's sales revenue (X) —measured in millions of dollars. Data for 21 companies who use the bank's services were used to fit the model: Yi = β0 + β1Xi + εi The results of the simple linear regression are provided below. Y = -2,700 + 20X, SYX = 65, two-tail p value = 0.034 (for testing β1) 10) Referring to Scenario 13-1, a 95% confidence interval for β1 is (15, 30). Interpret the interval. A) You are 95% confident that mean service charge (Y) will increase between $15 and $30 for every $1 million increase in sales revenue (X).B) You are 95% confident that the sales revenue (X) will increase between $15 and $30 million for every $1 increase in service charge (Y).C) At the α = 0.05 level, there is no evidence of a linear relationship between service charge (Y) and sales revenue (X).D) You are 95% confident that the mean service charge will fall between $15 and $30 per month. 11) In a multiple regression problem involving two independent variables, if b1 is computed to be +2.0, it means that A) the estimated mean of Y increases by 2 units for each increase of 1 unit of X1, holding X2 constant.B) the estimated mean of Y increases by 2 units for each increase of 1 unit of X1, without regard to X2.C) the estimated mean of Y is 2 when X1 equals zero.D) the relationship between X1 and Y is significant.

Chapter 10 Homework, Part 11 Exercise 10-11 Labour and Variable Manufacturing Overhead Variances [LO3, LO4] 1 Affordable Electronics Inc. manufactures medium-quality, reasonably priced wireless speakers for home use. The company uses standards to control its costs. The labour standards that have been set for one speaker are as follows: 10 points Standard Hours Standard Rate Standard Cost 12 minutes (0.20 hours) $19.00 $3.80 eBook During July, 3,850 hours of direct labour time were recorded to make 18,000 units. The direct labour cost totalled $74,305 for the month. Required. Ask 1-a. What direct labour cost should have been incurred to make the 18,000 speakers? (Do not round intermediate calculations.) Direct labour cost Print References 1-b. By how much does direct labour cost differ from the cost that was incurred? (Indicate the effect of variance by selecting "F" for fourable, "U" for unfavourable, and "None" for no effect (i.e., zero variance).) Total variance
