A 3/4-6 ACME threaded screw is used to lift a 2 kN load. Note that this has a pitch of 1/6. The mean collar diameter is 4 cm. Find the torque to lift and to lower the load using a ball-bearing thrust washer. What are the efficiencies? Is it self locking? You will need to look up ACME thread size standards online for this problem

Q1 / An axial load of 75 kN was applied to a steel rod
of 3 m in length and 0.025 m in diameter. Calculate the change in
length (∆L), Poisson’s ratio, percent elongation and percent
reduction in
area. Take change in diameter (∆d) = 5.73 x10 mm and E = 200 kN /
mm .

Test the significance of the correlation coefficient.
Then use math test scores (X) to predict physics test scores
(Y). Do the following:
Create a scatterplot of X and Y.
Write the regression equation and interpret the regression
coefficients (i.e., intercept and slope).
Predict the physics score for each....

A 6-m span simply supported beam carries a uniformly distributed
ultimate load of 70 kN/m. The dimensions of the beam section are b
= 300 mm, d = 700 mm. The beam is reinforced with bars of 25-mm
diameter in one row. f’c = 25 MPa, and Fy = 420 MPa. Use
