You have two materials to choose from to make a thermometer out of. The material property (let's call it A) you plan to use varies with Temperature T as follows for the two materialsMaterial 1: A(T) = 3T+ (7 * 10^-6) T^2Material 2: A(T) = 6.3 T+ (0.001)T^2Which material would you choose? Justify your choice with an explanation.

Solution A(T)=3T+(7*10^ - infty )T^ 2 the material 1 should be chosen. Because this material…

A tentative rule was given about tipping in Testing Experiment Table 8.4, where if a vertical line passing through the object's center of mass is within the object's area of support the object does not tip. According to the rule, the full box of crackers in the following experiment, which has a width of 13 cm and a height of 20 cm, was seen to tip at an angle of: θc=tan−1(13 cm/20 cm)=33∘θ According to the rule, at what angle will a box with the left half filled with crackers begin to tip? Assume the box is light-weight and that the contents remain in the configuration in
You are designing a hydraulic lift for an automobile garage. It will consist of two oil-filled cylindrical pipes of different diameters. A worker pushes down on a piston at one end (d = 25cm), raising the car on a platform at the other end (d=?). To handle a full range of jobs, you must be able to lift cars up to 3000 kg, plus the 700 kg platform on which they are parked. To avoid injury to your workers, the maximum amount of force a worker should need to exert is 100 N. What should be the diameter of the pipe under the platform? If the worker pushes down with a stroke 50 cm long, by how much will he raise the car at the other end?
