The compressive strength of concrete is normally distributed with μ = 2500 psi and σ = 50 psi. Find the probability that a random sample of n = 5 specimens will have a sample mean diameter that falls in the interval from 2499 psi to 2510 psi.

You can still ask an expert for help

An elevator (mass 4850 kg) is to be designed so that themaximum acceleration is 0.0600g. What is the maximum and the minimum forces the motor should exert on the supportingcable?

I already know how to find the maximum force (just multiplyingthe maximum acceleration by the mass), but I've got no clue as tohow to find the minimum acceleration when no minimum accelerationhas been found.

A small block with mass m is placed inside an inverted conethat is rotating about a vertical axis such that the time for onerevolution of the cone is T. the walls of the cone make an angle Bwith the vertical. The coefficient of static friction betweenthe block and the cone is ?. Draw a free body diagram.If the block is to remain a constant height h above the apex of thecone, what are the maximum and minimum values of T?

The arm weighs 44.0 N. The force of gravity acting on the arm acts through point A. Determine the magnitudes of the tension force t in the deltoid muscle and the force s of the shoulder on the humerus (upper-arm bone) to hold the arm in the position shown.

t=N

s=N

t=N

During light activity, a 70-kg person may generate 200 kcal /h. Assuming that 20% of this goes into useful work and the other 80% is converted to heat, calculate the temperature rise of the body after 1.00 h if none of this heat were transferred to the environment.
