1) Prof. K. climbed a wall and is now stuck and hungry. One of her ME 242 students saw this opportunity to test one of their pulley mechanisms to lift some pizza boxes for Prof. K. If the student is pulling the free end with a velocity of 2.75 ft/s. a) What is the mechanical advantage between the student and the pizza boxes? Hint: The link between pulleys 1 and 4 is rigid (meaning that they must move together. This is the key to solving this problem! b) What is the velocity of the pizza boxes?

QUESTION 9 The next 6 questions are 'open-ended'. You only need to do 5 of them. In question 15 I will ask which 5 you want me to grade. You must upload the scratch paper you used for these questions after you finish the text. A simple pulley system consists of two masses connected by a thin rope. Mass A, 5.0 kg, is initially on the floor, and mass B, 10.0 kg, is initially 2.00 m in the air. If the system is released from rest, what is the speed with which mass B hits the floor? You can ignore friction. 2.00 m Enter the speed in meters per second -- only type in the number (do not include the 'm/s'). Click Save and Submit to save and submit.

A tree contractor has been hired by a homeowner to remove a k damaged tree from a previous storm. The top of the tree broke off, leaving the trunk in the ground. The arborist will remove the tree by attaching a rope near the top and cutting the base close to the ground. The scenario is shown in the figure. 2 The distances in the figure are z = 14.7 m, h 1.45 m, h y = 5.66 m and x = 10.64 m. If the arborist pulls on the rope 1.. with a force of magnitude F 35.1 N, write the expression X for the torque T with respect to the base P of the tree using ijk unit vector notation, i i = T,i + Tyj + t;k where Tx, Ty» and Tz are the values of the torque components in the x-, y-, and z-directions, respectively. = N•m
