Chapter 12, Problem 10P

A steamer has waterplane area 1680m2 recorded in water with relative denisty 1.013. Displacement = 1200 t, calculate difference in draught in salwater reltive denisity 1.025.

relative velocity 11.72 m/s is correct, need help finding the angle please

Determine the distance between the two automobiles 2 s after A has passed through the intersection.

A box barge 65 m long and 12 m wide floats at a draught of5.5 m in sea water. Calculate:(a) the displacement of the barge,(b) its draught in fresh water

what is the angle of the velocity of block B? velocity is 7.46 in/s Determine the acceleration and angle of block B. (Round the acceleration value to three decimal places.)

Determine the relative velocity of B with respect to A.

Generate the kinematic diagram of the following mechanism. Then, draw their graphs and calculate their degrees of freedom (DoF) using Gruebler's formula.

An elastic bar of length L = 1m and cross section A = 1cm2 spins with angular velocity ω about an axis, as shown in the figure below. The radial acceleration at a generic point x along the bar is a(x) = ω2x, where ω= 100rad/s is the angular velocity. The bar is pinned on the rotation axis at x = 0. A mass M = 1kg is attached to the right end of the bar. Due to the radial acceleration, the bar stretches along x with displacement function u(x). The displacement u(x) solves the BVP (strong form) sketched below:              d dx (σ(x)) + ρa(x) = 0 PDE σ(x) = E du dx Hooke’s law (1) u(0) =?? essential BC σ(L) =?? natural BC where σ(x) is the axial stress in the rod, ρ= 2700kg /m3 is the mass density, and E = 70GPa is the Young’s modulus   1. Define appropriate BCs for the strong BVP 2. Find the solution of the strong BVP analytically 3. Derive the weak form of the BVP.
