Two collars C and D move along the vertical rod as shown. Knowing that the velocity of collar C is 50 in/s downward, find the instant centers of all three bars, the angular velocity of AB, the velocity of collard D.
It is necessary to design a square-section composite bar that will withstand an applied load without deflecting more than a specified amount.The design specification for the bar, including its dimensions and loading criteria, is given below.
the piston of a piston-cylinder device containing gas has a mass of 60kg and a cross-section area of 0.04m. the local atmospheric pressure is 0.97bar, and the gravitational acceleration is 9.81ms. determine the pressure inside the cylinder?
determine the values of Q that minimizes unit sales cost UC = TC/Q; and compute the annual profit earned by the plant at this quantity.
calculate the kg mix- ture from the mixer, kg water evaporated, and kg jam produced.
block c starts from rest and moves downward with a constant acceleration. knowing that after 5 s the velocity of block a relative to block d is 8 ft/s, determine a) the acceleration of the block c. b) the acceleration of portion e of the cable.
A cylindrical drill with radius r1 is used to bore vertically a hole through the centre of a sphere of radius r2.
The wheel of a crane lift is rolling on a flat rail. The radius of the wheel is 4 in, the contact length and force are 2.5 in and 1 ton respectively, and E = 30 MPa and ν = 0.3 for both parts. Determine (a) the maximum contact pressure, (b) the wi..
Steady State Thermal analysis can be use to simulate and obtain results to support the design optimization / objectives
Remember that velocity is a vector quantity so find the magnitude of the average velocity and the angle of average velocity from the horizon
No heat interactions with the environment are allowed. You do not need to describe the details of the process that produces the maximum work, but you do need to describe the final state of the blocks fully.
If the maximum shear stress is limited to one-half of its yield strength and the fillet radius is 0.3 in, what is the maximum torque that can be applied? What power could be transmitted by a similar shaft rotating at 400 rpm?
An auto speedometer is graduated in 5 mph increments and has an accuracy rated to be within ±4%. Estimate the uncertainty in indicated speed at 60 mph.
