Two people apply forces P1 and P2 to the handle of a wrench as shown.
(a) Determine the x and y components of the resultant force vector applied to the handle of the wrench.
(b) Determine the t and n components of the resultant force vector. Comment on why the t and n components might be useful to know.
the air inside a chamber at 54 c is heated convectively with heat transfer coefficient of 35 wm2k by a 0.29-m thick
the molar volume cm3mol of a binary liquid mixture at t and p is given by v 120x170x215x18x2x1x2a find expressions for
consider liquid flow between two horizontal parallel plates flowing left to right. given that the flowrate q must
A temperature measurement device is calibrated to produce 4-20 mA for a temperature operation range of 0-100 degree C. Sketch the input-output characteristic chart of the device, assuming linear input/output relationship.
Figure P4.45 shows a plastic beam having a box section, where the top plate is cemented in place, as indicated. All dimensions are in millimeters. For the 12-kN load shown, what is the shear stress acting on the cemented joint?
the vertical load on the hook is 1000 lb. draw the appropriate free-body diagrams and determine the maximum average
Solve for the pressure of a gas using both equations at a temperature of 400K and a molar volume of 1x 10-4 m3/mol. For the van der Waals EOS, use parameters of a= 4.1x10-1 (m3/mol)2 Pa, and b=4.3x10-5 m3/mol.
The plastic stress-strain curve for the material is given by ( σ = 500 ε 0.25 MPa). The tube is subject to axial load F and internal pressure p so that the stress ratio σθ/σz = 3.0 at all times. The deformation continues until the effective stress..
If you have a plane wall separating hot and cold fluids at temperature T(infinity)1 & T(infinity)2. Using x=0 & x=L as boundary conditions, determine what the heat flux would be in terms of T(infinity)1, T(infinity)2, h1, h2, k, L.
