A man weighs a fish with a spring scale attached to the ceiling of an elevator. Assuming I understand the setup, the spring scale will read the tension in the string. Problem Statement: A block of mass m = 15 kg is attached to a spring of stiffness K = 100 N/m. (4.0 kg)(9.80 m/s2) ! Procédure. Would the answer be 98N since both masses are the same? The coin weighing problem with a spring scale is the follow-ing [S60]: Suppose we are given n coins out of a collection of coins of two distinct weights w0 and w1, true and coun-terfeit coins, respectively.2 Assume we are allowed to weigh subsets of coins in a spring scale. Assuming there is no friction, determine the acceleration of the block when the spring has stretched by a length x = 0.02m. The spring is stretched by a distance X 1. a. Hooke's law is a law of physics that states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, F s = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring. Kitchen scales are a descendant of the traditional weighing scale. Il y a 9 années. 9 years ago. Example Problem 8-2: Deflection of Springs and Spring Scale (cont’d.) All the program code java source code should be zipped and submitted via Blackboard. A small sphere of mass m and density D is suspended from an elastic spring. The spring scale has a constant reading of 22.5 N. The answer is 1 m/s ^2. Determine the weight of each coin in a minimal number of weighing.
