(1 point) A single threaded square thread power screw has a major diameter of 64 mm and a pitch of 6 mm. There is a 10 kN load applied to the top of the screw. There is a 80 mm collar on the screw. The coefficient of friction is 0.12 for all materials. What is the torque required to raise the load? Report your answer in Nm to one decimal place.

The following question continues the exercise to connect the Riemann sum and the Fundamental Theorem of Calculus (2/3): Use the definition of a definite integral with right endpoints to calculate the area under the curve of f ( x ) = x 3 + 1 {“version”:”1.1″,”math”:”f(x)=x^3+1″}for 0 ≤ x ≤ 3. Note: This is the definition with lim n → ∞ ∑ i = 1 n f ( x i ) Δ x {“version”:”1.1″,”math”:”\lim_{n\to\infty}\sum_{i=1}^n f(x_i)\Delta x”}The following equations will be helpful for this question. ∑ i = 1 n i = n ( n + 1 ) 2 {“version”:”1.1″,”math”:”\sum_{i=1}^n i=\dfrac{n(n+1)}{2}”} ∑ i = 1 n i 2 = n ( n + 1 ) ( 2 n + 1 ) 6 {“version”:”1.1″,”math”:”\sum_{i=1}^n i^2=\dfrac{n(n+1)(2n+1)}{6}”} ∑ i = 1 n i 3 = n 2 ( n + 1 ) 2 4 {“version”:”1.1″,”math”:”\sum_{i=1}^n i^3=\dfrac{n^2(n+1)^2}{4}”} Select an option from below:
