The figure shows a rigid body oscillating about the pivot A. If Jis mass moment of inertia of the body about the axis of rotation, its natural frequency for small oscillations is proportional to c.g. (a) J (b) J2 id)

Problem 3: A small gearing system in your brand-new 3D printer fails as you were printing, leading to an overload in the motor and a fire in your home. The fire spreads, burning half of Everglades National Park in the worst environmental disaster in US history. The printer company blames you! Stating that you must have been misusing the printer some- how. Use your engineering knowledge to "show those jerks you mean business!" You investigate and find a serial number on the gears and type it into Google, finding the company that manufactures the gears. Their website provides some info that this series of gear is made from AISI 4340 steel and the yield strength is 125 kpsi. Assuming each gear tooth acts as a small cantilever, prove to the 3D printer company that they are liable for the fire. oct # Gear Information Gear radius (r): 1.00 in Tooth length (1): 0.15 in Tooth height (h): 0.15 in Tooth thickness (b): 0.1 in Angular velocity (w): 0.1 rad/s Motor Information Power (H): 0.009 hp 1…

Handwriting not allow please And give me complete answer

A machine makes two components; call them types A and B. It takes 250 seconds to switch production between the component types. During that time, no production occurs. When in production, each unit of A or B requires 0.5 second to be completed. The two components, A and B, are combined in an assembly process to make a final product; call it C. The assembly step can combine the two components into 1 unit every 2 seconds, or 30 units per minute. Assume there is ample demand. Suppose the machine rotates between one batch of 1,000 units of A and 1,000 units of B. What is the average inventory of B components? answer:______units

hints: The flask will be filled with water (at a constant rate of 500 gallons per minute). It will take me exactly 10 minutes to escape from the chains. The diameter of the tank at 1 foot intervals. I am 5 feet 9 inches tall, and I'm pretty skinny so that you can ignore both my volume and the volume of the stool in your analysis. A gallon is equal to 0.13368 cubic feet.  You can think of the volume and the height of the water as functions of time. You can easily find an expression for V (t), and then use your expression for volume in terms of height to solve for h(t). after 10 minutes amount of water in the tank=66.84 ft3 t=69.3 minutes h(t)=e66.84t/100pi  -1 h(10)=e66.84(10)/100pi  -1=7.39 ft  Height of stool=1.64 ft Height of water in the tank=7.39 ft Questions: show work How fast is the water rising?  I would like to know how long I will have to hold my breath during the last part of the stunt.

I need help solving problems 10, 11, and 12 pertaining to the print provided.

i cant see the full workings out even on a pc, please present again so that i can see the whole answer. please make it easy to follow

Please and explain step by step, instructions given at top

True, False or Uncertain. Explain your answer. Own wage elasticity JELLlincrease if product demand elasticity n? is high. In short run, when there is an increase in wage rate, each firm will hire less labor and so the industry labor demand is simply the horizontal summation of firm's labor demand. а. b. Labor demand is represented by the marginal revenue produce schedule (MRP) when we have competitive product market while it will be represented by the value of marginal product schedule (VMP) when we have a product market monopolist. When elasticity of substitution, SLK, increase that means the L and K are less substitutable, and the isoquant will be L-shaped. Minimum wage imposed by the government is always bad for the economy because it increase unemployment and deadweight loss. с. d. e. 3.
