The uniform 6-kg slender rod rests on the top center of the 3kg block. If the coefficients of static friction at the points of contact are ua=.4 and ub=.6, and uc=.3, determine the largest couple moment M which can be applied to the rod without causing the block to tip.
Immediately before failure, the testing machine records a force (F) of 50N, and a deformation (δ) of 2mm. We need to determine the maximum flexural strength (σ)
Block B of the mechanism is confined to move within the slot member CD. If AB is rotating at a constant rate of AB = 3rad/s, determine the angular velocity and angular acceleration of member CD at the instant shown.
If the bullets stick to the block and they move together find the velocity of the final system and find the total impulse of each bullet if the movement takes 0.5s before coming to a stop.
A project that will cost $750,000 will require payments as certain milestones are met. The initial payment is $50,000. When 30% of the work is complete an additional payment of $200,000 is due. When 70% of the work is complete another payment of $..
Consider two-dimensional flow over the double-wedge airfoil shown. Find the lift and drag per meter span acting on the airfoil and sketch the flow pattern. Find the pressure acting on all surfaces.
Calculate the ultimate tensile strength (engineering) of a material whose strength coefficient is 700 MPa and a tensile test specimen which necks at an engineering tensile strain of 0.35.
A slotted disk and opto-interrupter outputs pulses at 62 HZ. The disk has only one slot cut in it. what is the rotating speed of the disk in rpm?
A 40 mm diameter hole is drilled 3 m deep into the steel shaft. When the two torque are applied, determine (a) the maximum shear stress in the shaft: and (b) the angle of rotation of the free end of the shaft. Use G= 83GPa for steel.
The car travels up the hill with a speed of v = (0.4s) m/s, where s is in meters, measured from A. Determine the magnitude of its acceleration when it is at point s = 50 m, where p = 500 m.
a fully loaded lorry has a mass of 10 tonnes and is travelling along a road at uniform velocity when the brakes are applied and the lorry is brought to rest. if the deceleration is 2m/s2 and the coefficient of rolling friction is 0.15, determine t..
If the instrument weighs 85N, find the necessary static deflection of the isolator.
