Repost from اللجنة العلمية ميكاترونكس د11
التصويت للدكتور لاجل يشوف لنا حل قبل يرفع اعمال السنه الاخيره 👍
اذا كان اكثر من 40% ناجحين لن يصل الى الدكتور
وانتم ورجالتكم

The centerifugal tension depends on
1- mass per unit length
2- ✅both speed and mass per unit length
3- speed
4- none of them
A rod AO 150 mm link is initially at horizontal (150i) unticlockwise rotate about O with constant velocity. 5rad/s the its angle after 2.5second
1-143° from positive y axis
2-✅ 53° from positive y axis
3- 56°from positive x axis
4- 53 from positive x axis
If the coefficent of friction= 1/(3)^0.5, for the body to just start sliding the angle of inclination must be...
Maximum Tension of belt =2500N around a pully of 600mm major diameter and angle of contact 150 degrees, the shaft rotates with n=400rpm, and coefficient of friction =0.25. Find the power, torque, slack tension...
A wheel rotates about its axsis has two points A,B along its horizontal radius Rab=300mm, Va=80,Vb=140. Find the radius and the angular velocity
1) cubical block rests on an inclined plane when the block just slides down the inclined plane what will be the inclination:
a.40° b. 45° c.30° d.20°
2)two points A and B are located along horizontal radius of a circle where Rab=300mm, and the linear Velocities of A and B are 80 , 120 respectively determine (I)the radius of the circle:
a.0.9m b. 0.7 c.0.6 d.?
(II)Vab
3) A disc is rolling without slipping on a horizontal surface. Instantaneous centre of any point on the is located by:
a.the center of the disc b.the point of contact with the ground c.? d.?
4)belt with maximum tension of 2500N, coefficient of fraction of 0.25,lap degree of 150° , pulley radius of 300mm, and V of 400 rpm determine:
(I) the torque
(II) the power transmitted
