Given that a freight elevator has a weight limit of two tons each crate that is loaded onto the elevator weighs 80 pounds. The number of the crates will be calculated as below:-2 tons = 2000 pounds. Number of the crates = 2000 / 80. Number of the crates = 25. Therefore, the greatest number of crates that can be loaded will be 25.
So,8 adult male passengers can have a mean weight of up to 1368/8=171. If the elevator is loaded with 8 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 171 lb. (Assume that weights of males are normally distributed with a mean of 177 and a standard deviation of 26 .)
The direct answer to your question would be: The Motor. The point of the counterweight is to reduce the overall force the motor has to apply to get the elevator moving and to stop it. The counterweight is designed to be approximately equal in weight to the elevator. So, when the elevator is stationary, the weights are balanced and the motor has

“In typical elevators, there is a counterweight attached to the other end of the pulley system equivalent to about the weight of the car at 50% loading,” it explains. “Counterweights don’t do all of the work in modern elevators, but they help stabilize the system and reduce the load on the elevator motor.”

If the average weight of a child is 80 pounds and the average weight of an adult is 160 pounds, write an inequality that states that x number of children and y number of adults cause the elevator to be overloaded The inequality is 4000 b. Graph the inequality. Because x and y must be positive, limit the graph to quadrant I only. Use the . 103 475 178 8 131 386 317 321
