Ex 5.8 Two 100-N weights are attached to a spring scale as shown. The systems shown below are in equilibrium (with m = 7.00 kg and θ = 27.0°). Leadership. Ignore the masses of the pulleys and strings and assume the pulleys and the incline are frictionless. EXPLORE COLLECTIONS CREATE + back to brit + co. Sign In Sign Up. Have two people each hold one of the two spring scales. 1. menu. This will be the weight on a scale that measures force, otherwise the scale will read it's mass as 4.0kg. We use Newton's second law to solve this problem. Economics. For this reason, a 1 kg reading on a spring scale refers to 9.8 Newtons of tension, and it scales proportionally. Im pretty sure the balance would just read 98 N since the tension above equals the weight of the mass below. Operations Management. Explore › guides › education › › Material. > What is the reading of a spring balance when a stretching force of 10 Newton is applied on the opposite sides at same time? Hang the object to be measured from the spring scale hook. 2. Accounting. Read the Newtons scale for force. The forces acting on the system are the normal force by the spring scale and the downward weight of the woman. Finance. Solution for A block is attached to a spring scale. Spring balances come in different sizes. This scale reads force in newtons. scale in (a) N. scale in (b) N. scale in (c) N. scale in (d) At the top of the spring balance there is a fixed end and at the bottom a free end which moves when a force is applied to it. 3. So let’s understand more about Hooke’s law by examining how the Newton spring balance works. You have a and m, you want F. F = 27.2*0.8 = 21.76N The scale on top would read slightly heavier due to also supporting the weight of the lower scale itself. You can do some interesting investigations of forces using two spring scales. We will mostly be using Newtons during the module. 2) Im having a little trouble with this one. If the spring scales are calibrated in newtons, what do they read? The Newton Spring Balance. Newton's second law states that the force applied to a body produces a proportional acceleration. This refers to the TENSION force with which the spring scale pulls on something. Two identical spring scales, like those used to weigh fish, or those found in physics class. The scale reads the tension in the string. Read the grams scale for weight. Introduction. Spring Scales. 2. Products. (sorry about the photo - dont know how to fix it) Homework Equations F=ma, W=mg The Attempt at a Solution 1) Seems easy enough. To Do and Notice. Does the scale read zero, 100 N, or 200 N -- or some other reading? To Use a Spring Scale: If the block is in equilibrium, what is the reading in the scale in Newtons? Management. In the figure below you can see the Newton spring balance in my laboratory. Subjects. Business. The tension in the string is 100 N. This is the force the string must exert up on either of the 100-N weights at either end of the string. If used to measure friction force, it is only done so indirectly. Marketing. Weight as in the force in newtons (N). F = ma. The watermelon pushes down with a force of F = mg = 4.0kg*9.8 = ~ 40N. Hang the object to be measured from the spring scales of F = mg = 4.0kg * 9.8 ~!
