A 140-lb construction worker punched a bamboo wall (the wall has a shearing strength of 241 MPa). His hand 3 inches in diameter is equivalent to 0.6% of the mass of his own body, and forms a circular shape with a compressive stress limit of 0.31 mPa before it bleeds. Find for: а. thickness in cm of the hole he made on the bamboo wall b. force he exerted to punch the wall c. maximum acceleration of his punch without bleeding his hand
A pile hammer of mass 1500 kg drops from a height of 600 mm on a pile of mass 750 kg.The pile penetrates 50 mm per blow. Assuming that the motion of the pile is resisted by aconstant force, find the resistance to penetration of the ground.
(c) A 2.00 kg block hangs from the end of a 1.50 kg, 1.00 m long rod, togat her forming a pendulum that swings from a fridionless pivot a the top end of the rod.

Fig. 3.19 shows a hammer of mass 6 kg and pivoted at A. It falls against a wedge of mass 1 kg which is driven forward 6 mm, by the impact into a heavy rigid block. The resistance to the wedge varies uniformly with the distance through which it moves, varying zero to R newtons.

The disk is free to rotate about its axis and it initially at rest. Compute the angular velocity (rad/s) of the disc immediately after the bullet is embedded. A R 500 m/s ANS. 1.2 rad/s
A riveting machine is driven by a 4 kW motor. The moment of inertia of the rotating parts of the machine is equivalent to 140 kg-m2 at the shaft on which the flywheel is mounted. At the commencement of operation, the flywheel is making 240 r.p.m. If closing a rivet occupies 1 second and consumes 10 kN-m of energy, find the reduction of speed of the flywheel. What is the maximum rate at which the rivets can be closed?

A ballistic pendulum is a device often used for measuring the velocity of a projectile. Assume to projectile fully embeds itself in the pendulum. If the projectile mass is 25 grams, the pendulum mass is 2.5 kg, and the vertical displacement of the pendulum after the collision is 12 cm, find the velocity of the projectile just prior to the collision. cm cm
a) Figure Q10 shows an illustration of a ballistic pendulum that is used for determining the velocity of bullets. The length L = 1.0 m and mass of the block A is M = 10 kg. When a bullet of mass m = 38 g is fired into the block, the pendulum swings to angle e = 26°. Calculate the velocity of the bullet just before it embedded into the block. Assume that bullet stays lodged in block A and the mass of the rod length 1.0 holding block A is negligible. [Answer in m/s] Answer of a is 372.23 m/s b) Given that the velocity of a bullet of mass m = 40 g that enters the block A of mass 10 kg in Fig Q10 is 280 m/s and length L = 0.9 m, calculate the maximum angle e in degrees that the block A will swing to before swinging back down.
