3.1.2. [Level 1] Block B has a weight of WB = 18 kg, and the rope at A is pulled down with a force of F = 67 N. What is the acceleration ÿ of block B, where yg is measured down to B? E3.1.2 A• B

A crate of 67 kg simply stands on the moving cart with constant acceleration a. The height from the center of gravity to the cart, L, is 1.2 m, and the angle = 12°. What is the maximum acceleration a (in m/s²) the cart can have without tipping over on the cart? The coefficient of static friction between the crate and the cart is μg = 0.55. Please pay attention: the numbers may change since they are randomized. Your answer must include 3 places after the decimal point. Take g = 9.81 m/s². 0.5 m 0.5 m L Your Answer: ● 0 Answer G

2. For the system below: a. Give an equation of motion for h. Note that the system has two inputs, p1 and p2. b. When h= 5, give the force exerted on the bottom of the tank. (Assume that the width and height of the opening at the bottom of the tank is negligible. The area of the bottom of the tank is A). h PA PI P2 PA R

Q3: As Engineer, you have been asked to calculate only the force in each members of the truss shown below (fig 3) after applying two forces on it (F1 and F2) which are (500 N and 0.8 kN) respectively. D -F1 4 m Fig 3 E F2 4 m A 5 m
