A square with the dimensions of .02m by .02m by .5m is attatched to a solid surface. If the forces on the rod are too large, it will either crush or be sheared off where it is atatched to the solid surface. If the rod can withstand either a maximum normal stress of 25kPa or a maximum shear stress of 10kPa
a) what is the largest allowable magnitude of F2 if F2=0?
b) what is the largest allowable magnitude of F2 if F1=0
A cylindrical rod with a length of 380 mm and a diameter of 10 mm is to be subjected to a tensile load. The rod must not experience plastic deformation or an increase in length of more than 0.9 mm when a load of 24.5 kN is applied.
if the aircraft is encountering a steady side wind of speed vw=10 mi/hr , at what angle (a) should the pilot direct the aircraft so that the absolute velocity is parallel to the runway
Calculate uniform load (in addition to self wt.) which will cause the section to begin cracking
one of the wells pumps at a rate of 1240 m3/day. the second well pumps at 850 m3/day.if the aquifer has a transmissivity of 2000 m2/day and a storage coefficient of 4x10^-4, when would the wells start interfering with each other.
A rectangular open channel with a width of 10 ft and n = 0.013 conveys a discharge of 300 cfs. The upstream portion of the channel has a slope of 10%, which then abruptly changes to a slope of zero downstream.
A log that is 2 ft in diameter is to be cut into a rectangular section for use as a simply supported beam. The material is wood select structural grade (Douglas Fir) with a specific gravity of 0.017 lb/in3.
two forces applied as shown to a hook support. knowing that the magnitude of P is 35 N, determine by trigonometry the required angle if the resultant R of the two forces applied to the support is to be horizontal and the corresponding magnitude of..
What is the concentration of tracer in the reactor 1 h after tracer addition is terminated? The reactor had an initial concentration of tracer of 1.0 mg/L when tracer addition commenced.
What would be the Horizontal and vertical component from this acting force see diagram
A finished 2 x 4 timber (actual size 1 5/8 in. x 3 1/2 in. x 10 ft long) is used as a fixed-end, fixed-end column. If the modulus of elasticity for the timber is 1600 ksi and a factor of safety of 3 with respect to failure by buckling is specified
At a certain altitude and time, a rocket's acceleration is 2.5 g. One gravity (g) is equivalent to 32.2 ft/s^2. What is the rocket's acceleration in meters per square second
