A differential equation encountered in the vibration of beams is d4ydx4=2D where x = distance measured along the beam; [x]=[L] y = displacement of the beam; [y]=[L] = circular frequency of vibration; []=[T1] = mass of the beam per unit length; []=[ML1] D = bending rigidity of beam; [D]=[FL2] Show that the equation is dimensionally homogeneous. Note that [F]=[MLT2] see Eq. (1.21:).

Please answer in four decimal places, in Nm. 03: What is the value of C.G. away from the wall? (in meters, two decimal places)
What trigonometric identity may be used to summarize an equation for calculating tension force (the long equation you'll use before replacing the values)? What do you think the role of mass is in determining the net acceleration of an item rolling down an incline? Friction is a significant factor. Why is the normal force no longer equal to the weight of all things on an incline?
A 45 grams (0.045 kg) golf ball of diameter equal to 43 mm fell into a 2m deep lake. Neglect inertia at the moment of impact. Assume viscosity of 1.12x10-3 Ns/m2 , water density of 1,000 kg/m3 and Cd=0.5. Sphere volume equals 4π r³ /3. 1. How long will it take from the moment it hits the surface until it gets to the bottom? 2. If one estimates the Cd with Cd=24/Re formula, the settling velocity would be unrealistically large. Why?

Most of you have seen car advertisements where the car manufacturerbrags about how fast one of its cars can go from 0 to 100 km/h. Accordingto the manufacturer, the BMW 750iL model can go from 0 to 100 km/h in6.7 seconds. This performance is usually measured on a test track. The engine in the car is rated at 243 kW at 5000 rpm. The car has a reported weight of 23 kN . Is the claim by the manufacturer justifiable? Well, to answer this question you may agree it would be more fun to drive toa BMW dealership and take the car for a test run on a racing track. But let us answer this question with the knowledge you have gained so far in this course. We need to make some assumptions first; we can assume that the driver weighs 900 N and the reported weight of the car includes enough gasoline for this test. Next, we convert the speed and the mass values into appropriate units.
I do not understand the questiona 1 Calculation of force experience d by cable connected to block A, why using equation P=F/t x s instead of using work done formula and what is Fa=4F Why i cannot just do like this: Work = Power x Time = 5W x 10s = 50 Joules Force = 50 Joules / 2 meters = 25 Newtons and can tutor explain other questions like what is the equation means
